The present invention relates to weapons systems and, more particularly, to a system and method for preventing enemy incursions into a designated area.
Armed forces often struggle to halt enemy forces from entering into or crossing through certain predefined areas. These areas may include stratigical points, well hidden areas in which enemy forces may engage in hostile activity without being traced, or physical borders. Enemy forces may attempt to enter or take over stratigical areas in order to engage in missile launching attempts. Otherwise, enemy forces may attempt to cross through certain stratigical areas or cross fixed borders. Identifying enemy intrusion into these stratigical areas requires continuous aerial surveillance or other type of surveillance and a constant effort to halt enemy action. Once enemy forces enter or cross through the stratigical area, a swift “sensing to striking” time is required in order to halt enemy forces. The constant surveillance requirement, followed by a swift and accurate striking capability is often unmet by many armed forces.
Defense industries are engaged in developing motion detection capabilities within confined areas and along borders, aimed to enhance early detection of hostile forces movement. Motion sensing is achieved using various detectors that are placed within the area of interest and communicate with a central command post, and indicate any motion within the selected area of interest.
The complete process of eliminating enemy forces from entering into or crossing through predefined areas requires an autonomous striking capability. This autonomous striking capability should supplement the accurate detection and complete the task of reducing the enemy forces from entering certain areas. This sensing and striking system should essentially “close off” entire areas or eliminate possible border crossing attempts by the enemy forces. Such an autonomous striking system is described below. The basic system described below may be added to any suitable conventional sensing system and allows swift and accurate enemy forces neutralization within predefined confined areas.
The various known sensing systems all work in a similar fashion. The sensors indicate the exact position and detect the motion of enemy forces within a predefined area of interest. The sensing systems are either deployed from an aircraft in various forms, launched using ground missiles or manually positioned by ground forces. Alternative sensing systems are aerial or other systems capable of identifying and tracking movement within a predetermined area.
The goal of the sensing systems is to fully cover a complete area of predetermined size and positively detect any enemy motion within the area. The sensing system transmits the position and motion of the enemy forces to a command and control center that can select an appropriate reaction in order to neutralize the threat. In most conventional striking systems, a command and control center is advised by the sensing system when enemy forces enter the selected area of interest. The command and control center must select and deploy conventional neutralizing agents. This “loop closing” process required in order to eliminate the missile launching threat is time consuming and is often inefficient.
Gorman, in U.S. Pat. No. 6,584,879, teaches a system for disabling time-critical targets within a designated geographical area. The system includes a plurality of guided missile launchers deployed in the geographical area. Each launcher includes a guided missile that is launched vertically. When a target is detected in the geographical area, a command center instructs one or more of the launchers to launch their guided missiles. The launched missile(s) then home in on the target, either autonomously or under external guidance. The Gorman patent is incorporated by reference for all purposes as if fully set forth herein.
The present invention, which we call Wide Area Neutralizer (WAN), is a method and system for autonomously neutralizing time critical and moving targets of various forms within a confined area. WAN is made up of numerous ground-placed autonomous launchers that deliver precise munitions to a predefined area. The WAN links to any form of sensing system that detects enemy force ground movement within the area of interest. The present invention automatically awakes upon reception of an activation signal from a sensing system or from a command center and autonomously delivers accurate munitions that neutralize enemy forces within the confined sensed area.
According to the present invention there is provided a weapon system including: (a) a plurality of WAN components, each WAN component including: (i) a warhead, (ii) a launch mechanism for launching the warhead, (iii) an aiming mechanism for aiming the launch mechanism to launch the warhead in a desired direction, and (iv) a controller that, upon receipt of a command to aim and launch the warhead, operates the aiming mechanism to aim the warhead in the desired direction and then operates the launch mechanism to launch the warhead; (b) a WAN component deployment mechanism for deploying the plurality of WAN components in a defended area; and (c) a command center for instructing the controller of each of at least one of the WAN components to aim and launch the warhead of the each WAN component at a target that has been detected in the defended area.
According to the present invention there is provided a method of defending an area, including the steps of: (a) deploying a plurality of WAN components in the area, each WAN component including: (i) a warhead, (ii) a launch mechanism for launching the warhead, (iii) an aiming mechanism for aiming the launch mechanism to launch the warhead in a desired direction, and (iv) a controller that, upon receipt of a command to aim and launch the warhead, operates the aiming mechanism to aim the warhead in the desired direction and then operates the launch mechanism to launch the warhead; (b) upon detecting and locating a target in the area: (i) to identifying which at least one of the WAN components should launch the warhead thereof towards the target, and (ii) commanding each identified WAN component to launch the warhead thereof towards the target.
A basic weapon system of the present invention includes a plurality of WAN components, a WAN component deployment mechanism and a command center. Each WAN component includes a warhead, a launch mechanism for launching the warhead, an aiming mechanism for aiming the launch mechanism to launch the warhead in a desired direction, and a controller. When the controller receives a command to aim and launch the warhead, the controller operates the aiming mechanism to aim the warhead in the desired direction and then operates the launch mechanism to launch the warhead. The WAN component deployment mechanism is for deploying the WAN components in the defended area. The command center is for instructing each controller of one or more of the WAN components to aim and launch its/their warhead(s) at a target that has been detected in the defended area.
Preferably, the WAN component deployment mechanism includes one or more precision guided munitions, in each of which at least some of the WAN components are housed prior to the deployment of the WAN components and from which the WAN components housed therein are released during the deployment of the WAN components.
Preferably, the weapon system also includes one or more sensors for detecting the presence of the target in the defended area and for reporting to the command center that the target is present in the defended area. Most preferably, the weapon system also includes a sensor deployment mechanism for deploying the sensor(s) in the defended area.
In some preferred embodiments the command center issues its instructions remotely. In other preferred embodiments, the WAN component deployment mechanism deploys the command center in the defended area along with the WAN components.
The payload of the warheads may be lethal or sub-lethal.
Preferably, each WAN component also includes a locator for determining the location of the WAN component when the WAN component is deployed. The WAN component's controller reports the WAN component's location to the command center.
In one set of preferred embodiments, each, of one or more of the WAN components also includes a base on which the launch mechanism is mounted. The aiming mechanism includes a plurality of arms for tilting the base to aim the launch mechanism. In another set of preferred embodiments, each of one or more of the WAN components also includes a base on which the aiming mechanism is mounted, and the aiming mechanism is operative to turn and elevate the launch mechanism relative to the base to aim the launch mechanism.
In some preferred embodiments, each of one or more of the WAN components includes a stacked plurality of warheads. Each warhead includes an eccentrically disposed munitions body. The launch mechanism of such a WAN component launches the warheads individually in succession. The aiming mechanism of such a WAN component turns each warhead, prior to the launching of the warhead, so that the warhead's munitions body faces towards the target. In the example of such a WAN component below, as illustrated in
Preferably, the warhead has an axis of circular symmetry. The launch mechanism spins the warhead about the axis of circular symmetry when launching the warhead.
Preferably, each warhead includes a timer. When the command center instructs a WAN component to aim and launch its warhead at the target, the command center instructs the WAN component's controller to set the WAN component's warhead's timer to detonate the warhead after a respective delay subsequent to the launch of the warhead.
The basic method of the present invention is a method of defending an area. A plurality of WAN components of the basic weapon system is deployed in the area. When a target is detected and located in the area, the WAN components) that should launch its/their warhead(s) towards the target are identified and commanded to launch its/their warhead(s) towards the target.
Preferably, the method also includes deploying one or more sensors in the area for detecting and locating the target.
Preferably, deploying the WAN components includes determining the respective locations of the WAN components. Identifying which WAN component should launch its warhead then is based on the respective locations of the WAN components.
In some preferred embodiments, each of one or more of the WAN components includes a stacked plurality of warheads. Upon receiving a command to launch one of the warheads, such a WAN component launches the topmost warhead in the stack.
Preferably, each warhead has an axis of circular symmetry. When a warhead is launched, the warhead also is spun about its axis of circular symmetry.
Preferably, each warhead includes a timer. When a WAN component is commanded to launch its warhead, the WAN component also is commanded to set is warhead's timer to detonate the warhead after a respective delay subsequent to launching the warhead.
In some preferred embodiments, the commanding of the WAN components to launch their warheads is effected remotely. In other preferred embodiments, a command center that autonomously commands the WAN components to launch their warheads is deployed in the area along with the WAN components.
Various embodiments are herein described, by way of example only, with reference to the accompanying drawings, wherein:
The principles and operation of a Wide Area Neutralize (WAN) according to the present in invention may be better understood with reference to the drawings and the accompanying description.
The WAN system is an automatic striking system that delivers accurate munitions to a predefined area within seconds from activation. The WAN system includes various independent sub systems called WAN components that are placed within the area of interest. Following ground positioning, each WAN component remains dormant for months and at the same time is ready for an activation and launching signal. An electric power source (such as a long-lasting battery) powers the WAN component signal receiver at all times and also powers all other electric WAN aiming and launching sub-units. Upon relevant signal reception, the receiver activates the WAN aiming and arming sub-units. Aiming is performed by the WAN processing sub-unit, which calculates the required warhead launch heading and angle. A WAN component electric motor system lifts and positions the warhead at a required launch beading and angle. A gas generator or other type engine launches the warhead upon relevant signal reception. The launched warhead contains a munitions body. The munitions body detonates at a certain height and position along the warhead flight route, releasing numerous metal fragments toward the ground, so a predefined area of destruction is created. This area of destruction is calculated to cover the entire radius of possible motion of the enemy forces from the time of sensor detection to the time of metal fragment ground impact. More than one warhead may be fired at a single area in order to ensure complete and vast coverage of a large area of interest.
The system includes the following sub-systems:
1. Weapon delivery system—the WAN components are packed into a PGM (precision guided munition)—type weapon delivery system such as a JDAM-based delivery system or a MLRS-based delivery system. The weapon delivery system is launched from an aircraft or from a missile launcher and is aimed at the predetermined area of interest. The weapon delivery system releases the WAN components at a pre-determined height above the ground. The WAN components are dispersed in the air and fall to the ground. A statistical analysis of the WAN components' spread ensures complete coverage of the area of interest.
2. WAN components—Each WAN component is an autonomous weapon striking component. Upon arrival at the ground the position of each WAN component is transmitted to a command center. The WAN components remain dormant, preferably for months or even longer, awaiting an activation signal from the command center. When the command center receives a signal from the sensing system, one or more specific WAN components is/are activated and a target position is transmitted to the WAN component(s). The WAN component(s) “wake(s) up” and aim(s) its/their warhead(s) at the required striking area.
3. Warhead—The warhead consists of a munitions body and, in some embodiments, a rocket or gas generator for launching the warhead. The warhead is stored within the WAN component and is launched when the WAN component receives a launching signal. The warhead is launched from the WAN component along a ballistic trajectory calculated by the WAN processing sub-unit. At a certain predetermined point along the trajectory, the munitions body explodes.
4. Munitions body—stored within the warhead and explodes at a predetermined position along the warhead trajectory. For military applications, where lethality is desired, the munitions body includes numerous typical metal fragments which are released toward the ground upon detonation. The metal fragments create a fixed, calculated destruction area that covers the last known enemy forces position and any likely movement from the last known position. Such metal fragments are an example of what is called a “lethal payload” in the appended claims. For civilian (police applications such as border control, the munitions body includes a device such as a net, or substances such as a mixture of tear gas an pepper gas, that repel and/or immobilize and/or incapacitate intruders without causing fatal injuries. Such a device or substance is an example of what is called a “sub-lethal payload” in the appended claims.
Referring now to the drawings, the major components of the system are illustrated in
In some embodiments of the WAN system, command and control center is a manned command and control center 111 that is remote from the rest of the system. Other embodiments of the WAN system are autonomous. In these autonomous embodiments of the system, command and control center 111 is deployed in area of interest 101 along with the rest of the system. In these autonomous embodiments of the system, command and control center 111 receives the position and direction of motion of enemy forces 106 from sensors 105, automatically selects one or more WAN components 104 to attack enemy forces 106 and transmits the appropriate activation signals to these WAN components 104. In yet other embodiments, the functionality of command and control center 111 is distributed between a remote manned portion and a local portion that is deployed in area of interest 101 along with the rest of the system. The local portion of command and control system 111 is configured so that the operators of the remote manned portion of command and control system 111 can switch the local portion between a remote control mode in which the operators of the remote manned portion operate the system via the local portion and an autonomous mode in which the local portion operates the system autonomously.
Various preferred embodiments exist for each of the sub-systems of the entire striking system. These preferred sub-systems embodiments are separately described in each of the following sections.
Weapon Delivery System Embodiments
Weapon delivery system 103 is designed to deliver and spreads WAN components 104 within area of interest 101. In one embodiment of the system, weapon delivery system 103 is a JDAM-based precision-guided munition (POM), similar to a GBU-31 or a GBU-32, launched from an aircraft. Numerous WAN components 104 are packed within each JDAM PGM. The number of WAN components 104 in each JDAM PGM depends on the physical size and volume of each WAN component 104. Packing optimization of WAN components 104 into a JDAM PGM is necessary.
An analysis of different packing options within the JDAM PGM diameter is described herein and in
Nominal diameter for the JDAM PGM: 457 mm
JDAM PGM wall thickness: 3 mm
In a second preferred embodiment of the system, weapon delivery system 103 is a MLRS (Multiple Launch Rocket System) PGM launched from a MLRS launcher. If WAN components 104 are packed into a MLRS PGM missile a WAN component packing optimization process is performed according to the WAN components' size and volume.
If the diameter of WAN components 104 is the nominal diameter of Weapon Delivery System 103, the WAN components 104 optionally are layered one over another within Weapon Delivery System 103. This embodiment is illustrated in
Small explosive charges in weapon delivery system 103 explode and disrupt the fuselage of weapon delivery system 103 a few hundred meters above the ground, causing all the packed WAN components 104 to randomly disperse in all directions. For each weapon delivery system 103 and WAN component 104 combination, a statistical analysis is performed to ensure that WAN components 104 hit the ground in a pattern such that the entire area of interest is covered by the WAN components' munitions. WAN components 104 activate following ground placement and transmit their exact position and status to the automated command center. WAN components 104 are now ready for activation when an activation signal is received from the command center.
The weapons delivery system also is used to deploy sensors 105 in area of interest 101.
WAN Component Embodiments
WAN components 104 remain dormant as long as no threat enters the area of interest. Upon enemy force 106 entry into sensing area 101, sensor system 105 detects the position and movement of the enemy. Sensing system 105 then transmits this information to the command center. The command center selects a single WAN component 107 or several WAN components 107 to react to the threat. An activation signal indicating the position and motion of target 106 is transmitted to the selected WAN components 107.
WAN components 107, which have been dormant from deployment until the activation signal arrival, undergo the required procedures for warhead activation and launching. When the command center transmits a launching signal to the activated WAN component 107, the warhead is fired.
WAN component 104 includes several sub-units that must be packed into WAN component 104, regardless of its type, shape and size. The following table lists the required sub-units and
A number of WAN component embodiments are envisioned. Any or all of such embodiments may be deployed in area of interest 101, depending on the anticipated threat. The WAN component embodiments are hereby described:
In one preferred embodiment of WAN component 104 a large diameter cylinder (about 450 mm—the inner diameter of a GBU-31 JDAM PGM) is used to house all required sub-units, aim and fire the warhead.
In this embodiment WAN component 104 includes a large packaging cylinder 201 with pan & tilt arms 206 that aim warhead 202 when an activation signal is received from the command center.
Upon WAN component 104 activation signal reception, arms 206 tilt WAN component 104 to the required heading and launch angle. When the command center transmits a launching signal, warhead 202 is launched towards that required heading and at that required launch angle.
In a second preferred embodiment WAN component 104 is “bowl shaped.” This component 104 contains all required sub-units previously described in this section only packed to fit into the specific component size and volume limitations. This WAN component 104 includes a circular shaped warhead 202 positioned at the center of the component, while all other required sub-units are placed in the perimeter and within warhead 202.
In the embodiment of
Warhead Embodiments
Numerous warhead 202 embodiments may be selected. The selection of warhead 202 depends on a number of factors. Warhead 202 size and shape determines the overall size and shape of the WAN component 104 that houses warhead 202 prior to its launching. The desired destruction area 110 may affect the type of warhead 202 selected. The desired warhead aerial track 108 and WAN component destruction area radius is also determined by the type of selected warhead 202. Each warhead 202 creates a specific destruction area 110 size and metal fragment density.
In one warhead 202 embodiment warhead 202 is launched vertically and detonates at a certain altitude above ground. This warhead 202 embodiment includes the following sub-units:
Vertical lift rocket 301 lifts warhead 202 to a desired position and altitude. An electronic control box 303 with communication and processing components measures the warhead altitude above the ground. When warhead 202 reaches the predetermined position at the desired altitude above the ground, central pole 302 explodes, releasing munitions bodies 304 in all directions.
In the embodiment of
In a second embodiment of warhead 202, as illustrated in
In a third embodiment of warhead 202, a circular “bowl shape” warhead 305 is used. Warhead 305 is placed within a WAN component 306, as shown in
Munitions Body Embodiments
The munitions body is an explosive unit densely packed with metallic fragments. Alternatively, a munitions body is an explosive unit densely packed with tear gas or pepper spray units. Alternatively, a munitions body is an explosive unit densely packed with a net that traps targets following explosion. The munitions body is carried within the warhead and is designated to explode at a certain point along the aerial track of the warhead. Upon detonation, the metal fragments packed inside the munitions body spread at a known particle density, creating a predetermined and calculated area of destruction. Various munitions body embodiments create a wide variety of destruction area sizes and particle densities. Depending on the warhead aerial track and detonation point, the munitions body particle density must be sufficient to completely neutralize any enemy movement within the designated area of interest.
In one embodiment of the munitions body a “stair style” munitions body is packed into any warhead. The munitions body detonates at a known altitude above the ground creating a destruction area that consists of various metal fragment densities. The innermost destruction area consists of metal fragments that detonate from the center munitions body segment. The second perimeter destruction area is made up of metal fragments that detonate from the second munitions body segment. A third destruction area is made up of metal fragments that detonate from the third munitions body segment.
In a second embodiment a circular “bowl shaped” munitions body is packed into any warhead. The warhead with the circular munitions body is launched from the WAN component at a fixed angle and velocity, so that a known ballistic course is performed. At a certain point along the warhead flight path, the munitions body detonates releasing numerous metal fragments toward the ground. This creates an area of destruction with variable size and fragment density as previously indicated in the warhead section of this document. In order to create a desired metal fragment density within the entire area of destruction, the “bowl shaped” munitions body contains various surface area faces, each creating a different particle density destruction area. The sum of all metal fragments surfaces creates a destruction area of known size and particle density which can ensure that any movement within the area is halted.
In a third and fourth embodiment a “football” shaped munitions body is packed into any to warhead. This munitions body may be a complete football shape, as illustrated in
In a fifth and sixth embodiment of the munitions body, a rectangular wedge shaped or cone shaped munitions bodies may be packed into any warhead. The angular munitions bodies are designed to create a more condensed destruction area.
While the invention has been described with respect to a limited number of embodiments, it will be appreciated that many variations, modifications and other applications of the invention may be made. Therefore, the claimed invention as recited in the claims that follow is not limited to the embodiments described herein.
