Description

BACKGROUND

The following relates generally to the electronic countermeasure arts, the unmanned autonomous vehicle arts, signal jamming arts, communications arts, satellite navigation and communication arts, law enforcement arts, military science arts, and the like. It finds particular application in conjunction with the jamming and hijacking of drones, and will be described with particular reference thereto. However, it will be understood that it also finds application in other usage scenarios and is not necessarily limited to the aforementioned application.

Unmanned or autonomous aerial vehicles (“UAV), more commonly known as “drones”, have become more and more prevalent in both the military and civilian context. Current, commercially available drones embody technology that was until recently, solely within the purview of governmental entities. The drones available to the civilian and military markets include navigation systems, various types of eavesdropping components, high-definition or real-time video output, long life lithium batteries, and the like. Furthermore, current civilian models may be operated by any individual, without regarding to licensing or regulation.

The propagation of civilian drone usage has resulted in invasions of privacy, interference with official governmental operations, spying on neighbors, spying on government installations, and myriad other offensive operations. Military usage of drones, including armed drones, has increased substantially as battery storage has increased and power consumption has decreased. This widespread use of drones has led to security and privacy concerns for the military, law enforcement, and the private citizen. Furthermore, drones have substantially decreased in size, resulting in smaller and smaller, while the capabilities of the drones themselves have increased. This poses a security risk for security personnel as the operator of the drone may be far away, making the determination of the operator's intent particularly difficult to ascertain.

The drones in use typically operate using multiple frequency bands, some bands used for control signals between the drone and the operator, GPS/GLONASS signals for navigation, and other frequency bands for video and/or audio signal transmissions. This use of multiple frequencies results in difficulty in effectively tailoring a jamming signal directed solely to the offending drone, without negatively impacting other, non-offensive radio-frequency devices.

Furthermore, current commercially available jammers, while illegal in some jurisdictions, are generally omnidirectional in nature. To avoid issues relating to non-offensive devices, these jammers typically are limited in radius from less than a meter to 25 meters. Those jammers having larger effective radii for signal jamming or denial require substantial power (plug-in/non-portable) or are bulky. A common problem with all of these jammers is their inability to specifically target a drone, while allowing non-threatening devices to remain operational. Furthermore, due to the distances, and heights, at which drones operate, the portable jammers currently available lack the ability to effectively jam signals that may be used by the drones. For example, such commercially available jammers for Wi-Fi or GPS will propagate a jamming signal circularly outward, rendering the user's own devices inoperable while within that radius. The unintended consequences of such jamming may cause vehicle accidents or aircraft issues, depending upon the strength and radius of the jammer being used.

In addition to the foregoing problems, current jammers lack the ruggedness associated with field operations. That is, the commercially available jammers are delicate electronics, not designed for use by soldiers in the field. As noted above, the commercial jammers currently available further utilize multiple antennae, each directed to a different frequency band. These are not ruggedized pieces of equipment, capable of being utilized in field operations by law enforcement, security, or military. The multiple antennae are prone to breakage during transport. Those rugged military or law enforcement jammers that are available are portable in the sense that they are backpack or vehicle born devices, requiring substantial training to effectively operate.

Previous attempts at hand-held or portable jammers utilized standard form-factors for hand-held weapons. However, these designs are intended to compensate for recoil as the weapon fires. Rifle form-factors typically utilize a two hand approach, with the hands being spaced apart to steady the rifle when firing. This hand placement, with the weight of the average weapon, can be tiring, particularly when holding the weapon on target. Generally, because the weapon fires so quickly, the aforementioned design does not necessarily adversely affect its use. However, with directed energy weapons, which must remain on target while active, this displacement of at least one of the hands away from the body of the operator, places considerable strain on the extended arm.

Thus, it would be advantageous to provide a ruggedized form factor directional drone jammer that provides a soldier or law enforcement officer with simple, targeted anti-drone capabilities. Such a jammer is portable, including power supply, and comprises a rifle-like form allowing the soldier or law enforcement officer to aim via optic, electronic or open sights at a target drone for jamming of the drone control and/or GPS signals, while preventing interference for other devices utilizing the jammed frequencies. Furthermore, it would be advantageous to provide a suitable form-factor that relieves arm strain while maintaining aim on a targeted drone.

DETAILED DESCRIPTION

One or more embodiments will now be described with reference to the attached drawings, wherein like reference numerals are used to refer to like elements throughout. Aspects of exemplary embodiments related to systems and methods for signal jamming and signal hijacking are described herein. In addition, example embodiments are presented hereinafter referring to a rifle-like apparatus that may be aimed by a soldier or law enforcement officer on a drone to disrupt control and/or navigation of the drone, however application of the systems and methods set forth can be made to other areas utilizing electronic countermeasures and privacy protection.

As described herein, there is described a portable countermeasure device, such as rifle-like or firearm form factor jammer, that can be aimed by a user at a drone, resulting in the disruption of control and/or navigation signals. In one embodiment, the portable countermeasure device includes multiple signal generators and associated amplifiers, producing disruptive, spoofing and/or jamming signals across multiple frequency bands. It will be appreciated by those skilled in the art that suitable disruptive signals may include, for example and without limitation, multi- or single frequency noise signals, alternative command signals, false data signals, and the like. In such an embodiment, a single antenna is coupled to the portable countermeasure device, capable of directing multiple frequency bands of disruptive signals toward a single target, forming a cone around the target. The portable countermeasure device may be self-contained, with replaceable battery packs, or receive power from an external source.

It will be appreciated that the various components of the portable countermeasure device, as described in greater detail below, may be added to an existing fire arm, an aftermarket rifle stock, or a firearm-like form factor having a customized body incorporating the various components. The portable countermeasure device may be aimed via iron sights, optical scope, or other means for directing the disruptive signals toward a targeted drone. Furthermore, the embodiments disclosed herein may be implemented without software, hardware, or other signal analysis means, enabling a soldier or law enforcement officer to use the portable countermeasure device without substantial training. Such a simplified implementation further ruggedizes the portable countermeasure device for use in harsh environments where weather, lack of resupply, insurgents, criminals, or the like, may operate.

Referring now to FIG. 1, there is shown a functional block diagram of a portable countermeasure device 100 in accordance with one exemplary embodiment of the subject application. As illustrated in FIG. 1, the portable countermeasure device 100 may be implemented in a firearm-like form factor, providing ease of use and familiarization with the user. Accordingly, the portable countermeasure device 100 provides a soldier or law enforcement officer with the ability to specifically target a particular drone with disruptive signals, while minimizing the impact of the generated signal on other, non-targeted devices. It will be appreciated that the various components depicted in FIG. 1 are for purposes of illustrating aspects of the exemplary hardware are capable of being substituted therein.

It will be appreciated that the portable countermeasure device 100 of FIG. 1 is capable of implementation in a variety of handheld or portable form factors, and the illustrations depicted and discussed hereinafter provide exemplary, and non-limiting, form factors contemplated hereunder. As shown in FIG. 1, the portable countermeasure device 100 comprises a body 102 including signal disruption components 104, e.g., at least one signal generator 106 and at least one amplifier 108. The illustration of FIG. 1 depicts a portable countermeasure device 100 that utilizes a dual-grip configuration, having a first grip 114 in location typical with the typical pistol-grip rifle, and second grip 115 in relatively close proximity to the first grip 114. In some embodiments, as illustrated hereinafter, the first and second grips 114 and 115 may be adjacent each other, with the second grip 115 cantilevered or angled forward, towards the front of the device 110 and the first grip 114 cantilevered or angled back towards the rear of the device 110. In other embodiments, as will be appreciated by those skilled in the art, the body 102 may, for example and without limitation, resemble a commonly used rifle, including, without limitation, M4 carbine, M14, AR-platform, or the like, comprising an upper receiver and a lower receiver, as well as other rifle designs, as will be appreciated by those skilled in the art including, for example, modular rifle designs, standard rifle designs, and the like. Depending upon the configuration of the portable countermeasure device 100, the signal disruption components 104 may be contained in the upper receiver, the lower receiver, or both.

The body 102 may be constructed of non-metallic materials, i.e., ballistic plastic, carbon fiber, ceramics, etc., or suitable non-transmissive metallic composites. The body 102 may be implemented in a suitable form factor with which soldiers and/or law enforcement personnel are already familiar, e.g., the aforementioned M4 carbine, AR-platform, AK-platform, SCAR, bullpup, etc. It will be appreciated that the width, length, and height of the body 102 may be dependent upon the size and number of generators 106 and amplifiers 108 either integral therein or externally affixed thereto. According to one embodiment, a multifunctional cell is formed as the body 102 to provide both structural support/shape of the portable countermeasure device 100 as well as supply power to the components therein. A suitable example of such a multifunctional cell is provided in PCT/US2013/040149, filed May 8, 2013 and titled MULTIFUNCTIONAL CELL FOR STRUCTURAL APPLICATIONS, the entire disclosure of which is incorporated by reference herein. In accordance with another embodiment, the portable countermeasure device 100 may include multiple signal disruption components 104 to combat a variety of potential targets, e.g., receivers of improvised explosive devices (IEDs), commercial drones, military drones, or other portable electronic devices of enemy combatants or suspects, e.g., cellular phones, GPS/Satellite-based navigation devices, remote control detonators, etc. A suitable example of a portable countermeasure device 100 that includes multiple signal disruption components 104 within the body 102 is depicted in FIG. 2A et seq., as discussed below.

The portable countermeasure device 100, as shown in FIG. 1, includes a first activator 110, located adjacent to the first grip 114, and a second activator 112, located adjacent to the second grip 115 on underside of the body 102. It will be understood that the portable countermeasure device 100 may be implemented with a single activator, whereby multiple disruptive signals are generated via the activation of the single activator. The activators 110-112, as will be appreciated, is operable to close a circuit or “firing mechanism” (not shown) to allow power to flow from the power source, e.g., backpack (not shown), AC power (not shown), or optional, battery pack (not shown), to the signal generator 106 and amplifier 108 of the signal disruption components 104. It will be appreciated that the activators 110-112 may be implemented as typical firearm triggers, toggle switches, spring-loaded buttons, or the like. According to one embodiment, the first activator 110 is operable to activate control circuitry for disruption of control frequency bands, while the second activator 112 is operable to activate control circuitry for disruption of GPS/navigation bands. An example implementation of the dual activators 110-112 is embodied in the portable countermeasure device 200 of FIGS. 2A-3F, discussed below.

In accordance with one embodiment, the signal generator 106 and corresponding amplifier 108, may be configured to generate signals from DC to 30 GHz. In another embodiment, a signal generator 106, with corresponding amplifier 108, is incorporated to generate disruptive signals in the, 70-75 MHz, 400-500 MHz, 800-900 MHz, 900-1000 MHz, 1000 MHz-1.8 GHz, 2.0 GHz-2.6 GHz, 5.0-5.6 GHz frequency ranges, or other known control/navigation signal frequency ranges. In one particular embodiment, a signal generator 106 for each of the 72 MHz frequency band, the 400 MHz frequency band, the 800 MHz frequency band, the 900 MHz frequency band, the 1.2 GHz frequency band, the 1.5 GHz frequency band, the 2.4 GHz frequency band, and the 5.8 GHz frequency band, with corresponding amplifiers 108 are incorporated into the portable countermeasure device 100. Additionally, the signal generator 106 may be in communication with memory (not shown) that stores alternative command signals for spoofing or hacking, as will be known in the art, a particular control frequency. In such embodiments, the signal generator 106 may be operable to transmit a different navigation signal (altering the coordinates the drone is receiving from navigation satellites/commands), transmit a control signal indicating the drone should land or return to home, or the like. It will be appreciated that such signals generated via the signal generator 106 may be output in addition to noise, jamming, or the like, or in place thereof.

In accordance with the example embodiment of FIG. 1, the optional battery pack (not shown) supplies suitable power to the disruptions components 104 of the portable countermeasure device 100. In one non-limiting example, the battery pack may be implemented as a rechargeable battery, including, for example and without limitation, a lithium-ion battery, a lithium ion polymer battery, a nickel-metal hydride battery, lead-acid battery, nickel-cadmium cell battery, or other suitable, high-capacity source of power. In other embodiments, a non-rechargeable battery may be utilized, as will be appreciated by those skilled in the art. According to one exemplary embodiment, the battery pack is implemented in a magazine form factor, capable of insertion into a battery well (similar to the magazine well of the lower receiver of a rifle). It will be appreciated that such an implementation will be natural to a soldier or law enforcement officer, allowing utilization of existing magazine carrying devices for carrying additional battery packs, familiarity with changing a battery pack, as well as maintain the balance of the portable countermeasure device 100 similar to those rifles with which the soldier or law enforcement officer is most familiar.

In accordance with another embodiment, the portable countermeasure device 100 may utilize an auxiliary cable to a backpack power supply, a remote power source, a portable generator, fuel cell, vehicle interface, or the like. As shown in FIG. 1, a suitable coupling 117 is illustrated as affixed to the buttstock 103, enabling the attachment of a suitable power cable from various sources, e.g., a battery stored in a backpack, hip/fanny pack, secured to MOLLE webbing, or the like. Furthermore, the skilled artisan will appreciate that the battery pack is not limited in form and can be complementary to the form-factor of the portable countermeasure device 100, for example, similar to a rectangular magazine, tubular magazine, and the like, as well as being integrated within the body 102 of the portable countermeasure device 100, i.e., a structural battery as discussed above.

According to another embodiment, the portable countermeasure device 100 may include a display 120 operable to display remaining power levels of the battery pack, effective range of the output of the signal disruption components 104 relative to power supply level, or the like. This optional display 120 may be connected to control components (not shown), and be customized to display the frequency selected for output by the jammer components 104. In such an embodiment, the display 120 may be implemented as an LED, LCD, OLED, or other suitable display type. In accordance with one embodiment, the display 120 of the portable countermeasure device 100 may be implemented as a visual indicator associated with operation of the various components of the device 100. It will be appreciated that as the portable countermeasure device 100 does not provide physical recoil when operated, the display 120 provides visual feedback to the operator. As indicated above, one or more LEDs, or other suitable visual indicators, may be utilized, indicating, for example and without limitation that individual circuit cards are powered up, that individual circuit cards are within specified limits, that power is on to the operating/selected antennae, which antennae are operating, and the like.

In accordance with another embodiment, the portable countermeasure device 100 is equipped with a haptic feedback component 121, configured to provide haptic feedback through the body 102 (or grips 114, 115) to the operator when the portable countermeasure device 100 is active. In varying embodiments, the haptic feedback component 121 may be activated when one or more triggers 110, 112 are engaged and power to the signal disruption components 104 is on. In such embodiments, the haptic feedback generated by the component 121 may differ so as to indicate which antenna(e) 122 is engaged. As with other directed energy devices, e.g., lasers, RF generators, radar jammers, etc. having weapons form factors used in electronic warfare, the portable countermeasure device 100 of the subject application the does not provide any observable recoil when activated. Accordingly, the haptic feedback component 121 may provide varying feedback to triggers 110 and/or 112, grips 114 and/or 115, buttstock 103, etc., indicating activation of the portable countermeasure device 100.

The portable countermeasure device 100 depicted in FIG. 1 utilizes a single, multi-function directional antenna 122, extending outward from the body 102 in a direction away from the user. It will be understood that other embodiments, as discussed below, may utilize multiple directional antennae in accordance with the number of disruptive signals to be generated, the types of disruptive signals, desired range, and the like, as illustrated in FIGS. 2A-3F, described below. It will be appreciated that, maintaining a suitable comparison to a rifle, the antenna 122 replaces the barrel of a rifle, thereby maintaining familiarity and ease of operation by the soldier or law enforcement officer. In accordance with some embodiments, the antenna 122 may be “hot-swappable” or “replaceable” in the field, allowing for different directional antennae to be used by the portable countermeasure device 100 in accordance with the battlefield conditions. For example, the distances involved in commercial drone disruption may utilize less power-intensive disruptive signals than military drone disruption. In such an embodiment, a suitable antenna may not need to be as large, or a different design antenna may be used. In another example, in the event that the antenna 122 is damaged while in the field, an expedient repair capable of being performed by the soldier or law enforcement officer is replacement of the antenna 122, as opposed to having to submit the portable countermeasure device 100 to an armorer or electronics specialist for repair, thereby keeping the portable countermeasure device 100 operative.

In one particular embodiment, the antenna 122 is implemented as a combined, high-gain, directional antenna having a helical cross-section. Other suitable directional antenna, e.g., Yagi, cylindrical, parabolic, long period array, spiral, phased array, conical, patch, etc., are also capable of being utilized in accordance with the disclosure set forth herein.

Affixed to the top of the body 102, either fixed thereto, or removably attached, e.g., attachments to a rail (shown in FIGS. 2A-3F), are “iron sights” 124A (with a corresponding sight 124B attached or fixed to the end of the antenna 122), allowing for aiming by the soldier or law enforcement officer of the portable countermeasure device 100 at a target drone. In other embodiments, particularly when the top of the body 102 includes the aforementioned rails, a wide or narrow field of view optical sight may be utilized to allow the soldier or law enforcement officer to target drones beyond the normal field of vision. To avoid unintentional disruption of nearby devices outside the disruption cone 126 directed by the antenna, the sight 124A and/or 124B may be constructed of a suitable non-metallic material. The disruption cone 126 may range from 0 degrees to 180 degrees, including for example and without limitation, 0 to 120 degrees, 0 to 90 degrees, 0-45 degrees, 20 to 30 degrees or variations thereof. The effective range of the portable countermeasure device 100 may extend outward from the antenna 122 at varying ranges, from 0 meters outward greater than or equal to 400 meters in accordance with the power supplied to the disruption components 104. Accordingly, it will be appreciated by those skilled in the art that the maximum range of the portable countermeasure device 100 may be extended or reduced in accordance with the amount of power supplied to the disruption components 104, the ratio of power to time on target, and the like.

In operation, the soldier or law enforcement officer will target a drone hovering or flying in an unauthorized area by aiming the antenna 122 of the portable countermeasure device 100 in a manner similar to a regular firearm. That is, the soldier or law enforcement officer, using the iron sights or optical sights 208, directs the antenna 122 of the portable countermeasure device 100 toward the drone. After ensuring that sufficient power is available, and the drone is within the effective range of the portable countermeasure device 100, the soldier or law enforcement officer activates the activator 110 (for all control frequency bands) and/or the activator 112 (for all GPS/navigation frequency bands) to activate the control circuit (not shown), which regulates the power from a battery or other power source to the disruption components 104. In an alternative embodiment, a single activator (not shown) may control activation of all disruption components 104, thereupon simultaneously or sequentially generating disruptions signals as described herein when the activators 110 and 112 are activated. When disrupting multiple frequency bands, e.g., control signals, Wi-Fi and/or GPS, multiple disruption signal generators 106 and amplifiers 108 are activated to produce the desired disruption signal, e.g., noise, spoofing, alternate commands, alternate coordinates, etc., on the selected frequency bands.

The disruptive signal is then directed through the single antenna 122 (capable of handling multiple frequency bands) or multiple antennae toward the drone at which the portable countermeasure device 100 is aimed. The disruption cone 126 then extends outward from the portable countermeasure device 100 toward the drone, disrupting control and GPS signals effectively negating the presence of the drone in the unauthorized area. Alternative embodiments disclosed herein include generating, via the signal generator 106, alternative commands to the drone, instructing the drone to land, change direction, change video broadcast stream, stop video streaming/recording, thereby overriding the original control signals.
