The present invention relates to countermeasures systems and, more specifically to a unit for displaying information about a countermeasures system in controlling a counter measures system.
Aircraft, as well as ships and land vehicles, that operate in combat zones are typically equipped with countermeasures systems that are used to confuse weapons fired at the aircraft. Such countermeasures systems typically include things like chaff and flares. Chaff is a radar countermeasure that generates a cloud of small, thin pieces of aluminum or metallized fibers. The cloud can be mistaken for a target by radar-guided weapons, such as missiles. Flares generate a heat signature similar to that of the frame deploying it and are used to lead heat-seeking weapons away from the airframe or other type of vehicle. Other types of countermeasures include expendable decoys and radar jamming circuits.
Existing countermeasures systems include a plurality of countermeasures dispensers (such as chaff dispensers and flare dispensers), which are activated by a programmer. The programmer is a control circuit with signal outputs that cause the dispensers to launch their countermeasures when activated. The programmer can be programmed with advanced threat evaluation routines that determine the type of incoming threat and with automatic response routines that launch specific combinations of countermeasures tailored to the type of incoming threat. The programmer provides data outputs and receives control inputs from a control unit that provides information to a user and that receives control inputs from the user.
Many NATO aircraft are equipped with an ALE-47 countermeasure dispenser system, which has been employed on the following airframes: F-16, F/A-18, C-17, CH-47 and UH-60. The ALE-47 is integrated with an aircraft's radar warning receivers, missile warning receivers and other electronic warfare sensors. When these sensors detect a threat, the countermeasure dispenser system can automatically launch countermeasures such as flares and chaff in pre-programmed mixes that correspond to the threat. The ALE-47 includes a cockpit control unit, sequencer units, countermeasure dispensers and an optional programmer. The cockpit control unit provides an interface with the pilot. The sequencer units control the dispensers. In the ALE-47, each dispenser holds up to five different types of countermeasures and the whole system can accommodate up to 32 dispensers on certain aircraft. The ALE-47 also includes a jettison switch, the activation of which causes the jettison of items that could inhibit the airframe in certain situations. For example, external fuel tanks can be jettisoned when entering a dogfight so as to reduce the airframe's drag and weight.
Existing control units typically include several dedicated switches to allow a pilot to cause deployment of selected countermeasures responses. Such control units also include test display to show the types and numbers of available countermeasures.
Typically, pilots also use an electronic warfare management system (such as the ALQ-213) that displays information from electronic warfare systems such as warning systems and jammers. Pilots often use information from both an electronic warfare management system and a countermeasures system to make threat response decisions and then they provide control inputs to both systems to execute those decisions.
Also, existing units use text displays, which require the pilot to expend mental energy and spend time comprehending the data while making countermeasures deployment decisions. Thus, the pilot may be temporarily distracted from other important events occurring configurations and performing system upgrades often requires changing hardware used in the control unit, which can be time consuming and expensive.
Therefore, there is a need for an integrated countermeasures and electronic warfare management system that provides a user with an intuitive interface for information and control.
There is also a need for a countermeasures system that can be easily reconfigured by software updates.
The disadvantages of the prior art are overcome by the present invention which, in one aspect, is a countermeasures control interface for use in deploying countermeasures from a frame in response to commands from a user. The countermeasures are deployed from a first countermeasure dispenser that deploys a first type of countermeasure and a second countermeasure dispenser that deploys a second type of countermeasure that is different from the first type of countermeasure. A programmable user interface, which is in communication with the control unit, receives the commands from the user regarding deployment of the countermeasures. The user interface includes a display that shows a plurality of user-selectable image formats, in which at least one of the user-selectable image formats includes a graphic representation of a current loadout of the first countermeasure dispenser, a graphic representation of a current loadout of the second countermeasure dispenser and a graphic representation of a plurality of currently-available options for deploying countermeasures. The user interface also includes a user input device that receives input regarding a countermeasure deployment choice from the user and generates a signal corresponding to the countermeasure deployment choice. An electronic circuit controls the display so as to generate the plurality of user-selectable image formats and that receives the signal corresponding to the countermeasure deployment choice from the user interface and selectively activates both the first countermeasure dispenser and the second countermeasure dispenser so as to cause deployment of the countermeasures according to the countermeasure deployment choice.
In another aspect, the invention is a countermeasures device for deploying counter measures from a frame in response to commands from a user, in which a first countermeasure dispenser is mounted on the frame and is configured to deploy a first type of countermeasure. A second countermeasure dispenser is mounted on the frame and is configured to deploy a second type of countermeasure that is different from the first type of countermeasure. A control unit selectively activates both the first countermeasure dispenser and the second countermeasure dispenser. A user interface, which is in communication with the control unit, receives the commands from the user regarding deployment of the countermeasures. The user interface includes a display that shows a plurality of user-selectable image formats, in which at least one of the user-selectable image formats includes a graphic representation of a current loadout of the first countermeasure dispenser, a graphic representation of a current loadout of the second countermeasure dispenser and a graphic representation of a plurality of currently-available options for deploying countermeasures; and a user input device that receives input regarding a countermeasure deployment choice from the user and that generates a signal corresponding to the countermeasure deployment choice to the control unit. The control unit controls the display so as to generate the graphic representation.
These and other aspects of the invention will become apparent from the following description of the preferred embodiments taken in conjunction with the following drawings. As would be obvious to one skilled in the art, many variations and modifications of the invention may be effected without departing from the spirit and scope of the novel concepts of the disclosure.
BRIEF DESCRIPTION OF THE FIGURES OF THE DRAWINGS
A preferred embodiment of the invention is now described in detail. Referring to the drawings, like numbers indicate like parts throughout the views. Unless otherwise specifically indicated in the disclosure that follows, the drawings are not necessarily drawn to scale. The present disclosure should in no way be limited to the representative implementations and techniques illustrated in the drawings and described below. As used in the description herein and throughout the claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise: the meaning of “a,” “an,” and “the” includes plural reference, the meaning of “in” includes “in” and “on.”
As shown in
In one embodiment, the control display unit 110 can be programmed to enter an automatic response mode that causes a predetermined deployment of countermeasures upon detection of a specific threat. For example, if an incoming missile from a known radar guided missile launcher is detected, then the system can be preprogrammed to deploy chaff and activate electronic countermeasures automatically in response.
In one embodiment, as shown in
As shown in
A programmable user interface allows the user to select the data displayed and to input commands regarding deployment of countermeasures. The display mode selections 312 allow the user (e.g., the pilot) to select the type and arrangement of information and control inputs that are displayed on the screen 310. In the example shown, the pilot can depress selection hard buttons 362 adjacent to “5” mode to show a predetermined countermeasures configuration; SEMI mode to show a mixture of loadout data for flares 320 and chaff 324, countermeasures combination (“cocktail”) selections 330, and threat location data 340; radar warning receiver (“RWR”) mode to show radar warning data on the display screen 310; jammer (“JMR”) mode to show jammer data; and missile warning system (“MWS”) mode to show information from the missile warning system. A detail soft key 314 allows the pilot to indicate the granularity of detail to be shown. The pilot can also jettison predetermined items (e.g., all available flares, external fuel tanks, missiles and/or bombs) by flipping the jettison switch 374 in response to current combat or landing conditions.
In the example shown, the pilot has selected the “SEMI” mode by depressing the hard button 362a adjacent to the “SEMI” label 312a displayed on the display screen 312. In this mode three panels are displayed on the screen 310. The leftmost panel 325 shows a graphical loadout of the current status 320 of each flare launcher and each chaff launcher 324. The different types of launchers may be represented by different shapes (e.g., circles for flares and rectangles for chaff) to facilitate easy recognition by the pilot. For example, in this example launcher 322 currently has 105 flares available and launcher 326 currently has 186 chaff units available. The center panel 329 shows four different available countermeasures deployment schemes 330 that the pilot can select by touching the displayed scheme. For example, the pilot can see that deployment scheme 4 has eight units available for deployment and the image of the cocktail glass 331 indicates that scheme 4 is a mixture of different countermeasures types that will be launched according to a predetermined launch pattern. The pilot's touching in the scheme 4 rectangle will cause a scheme 4 cocktail to launch according to the predetermined pattern. The pilot will have memorized each deployment scheme as part of the pilot's training. The rightmost panel 340 shows a polar coordinate image 342 that gives an indication of detected threats by showing a bearing and range of the threat with respect to the frame. They type of threat can be indicated by an icon, such as a caricature of the threat or a letter indicating the type of threat. In the example shown, an incoming missile has been detected near the one o'clock position as indicated by an “M” shown in a box.
