Description

Technical Field

[0001] This invention relates to the field of intelligent defense technology, specifically to a low-speed, small-target reconnaissance and countermeasure system and method. Background Technology

[0002] Targets flying at altitudes below 1000 meters, speeds less than 200 kilometers per hour, and radar cross-sections less than 2 square meters are generally classified as low-altitude, slow-moving, and small targets. Examples include drones, model aircraft, gliders, sky lanterns, and hot air balloons. These targets are not only inexpensive, easy to operate, portable, and readily available, but also exhibit sudden takeoffs, making them difficult to detect and counter. Therefore, reconnaissance and countermeasures against low-altitude, slow-moving, and small targets are of great significance.

[0003] Manual identification, tracking, and countermeasures can mitigate the threat posed by low-altitude, slow-moving, and small targets to low-altitude surveillance areas to some extent. However, with the increasing sophistication of camouflage technologies for low-altitude, slow-moving, and small targets, manual reconnaissance and countermeasures against these targets are not only inefficient but also inaccurate, failing to meet the demands for such reconnaissance and countermeasures.

[0060] In one embodiment, the reconnaissance equipment includes: radar equipment, optoelectronic equipment, and radio equipment;

[0061] Radar and radio equipment are used to detect the area of ​​the warning zone and report the radar and radio data of the detected suspicious low, slow and small targets so that the data processing module can generate guidance instructions based on the radar and radio data.

[0062] Optoelectronic equipment is used to adjust the azimuth, rotation speed and pitch of the turntable according to guidance instructions to track suspicious low-speed small targets and acquire optoelectronic data of the suspicious low-speed small targets.

[0069] Figure 2 This is a schematic diagram of the structure of a low-speed, small-target reconnaissance and countermeasure system provided in another embodiment of the present invention. (See diagram below.) Figure 2 As shown, the system may include: a service module, a data processing module, a data acquisition module, an equipment control module, a countermeasure strategy module, a data fusion module, and a data storage module. The database shown in the diagram could be, for example, a Linux database. The data processing module, data acquisition module, equipment control module, data fusion module, and countermeasure strategy module can constitute a reconnaissance and countermeasure module, used for reconnaissance and countermeasure against low-altitude, slow-moving, and small targets. The service module is used for user front-end input, including: the warning zone range, reconnaissance equipment information, countermeasure equipment information, countermeasure strategy information, comprehensive situation display information, and intelligence information compilation. The service module is connected to the reconnaissance and countermeasure module; the data processing module is connected to the data acquisition module, data fusion module, and countermeasure strategy module; the data fusion module is connected to the countermeasure strategy module; and the data acquisition module is connected to the equipment control module.

[0070] The equipment control module includes a detection module, an alarm module, and a countermeasure module. The control module receives commands and controls these modules, primarily controlling the turntable's azimuth, rotation speed, and pitch. The detection module is mainly used to detect low-altitude, slow-moving, and small targets and reports these targets to the data acquisition module. The alarm module includes an audible and visual alarm, which receives alarm commands from the data processing module and controls the alarm to sound. The countermeasure module is used to counter high-threat low-altitude, slow-moving, and small targets. Specifically, the detection module includes radar equipment, optoelectronic equipment, and radio equipment. The continuous operation of the radar and radio equipment detects suspicious low-altitude, slow-moving, and small targets within the detection zone. Radar data and radio data of these targets are acquired through the radar and radio equipment, respectively. The radar and radio data are fused, and guidance commands are generated based on the fusion results to guide the optoelectronic equipment to track the suspicious targets and acquire their optoelectronic data. The countermeasure module may include laser equipment, radio jamming equipment, and navigation decoy equipment. The countermeasure module uses laser countermeasures, forces the drone to land, or performs navigation deception operations based on the target's countermeasure strategy.

[0071] The data acquisition module is used to collect data on suspicious low-speed, small targets uploaded from the device control module. The data acquisition module includes a communication module and a protocol parsing module. The communication module is used for communication with the device control module, and the protocol parsing module is used for parsing the communication data according to the protocol.

[0072] The data processing module processes data returned from the data acquisition module and information returned from the countermeasure strategy module. It includes an instruction generation module, an instruction issuance module, a data upload module, a data parsing module, and a device guidance module. The instruction generation module dynamically generates countermeasure instructions, alarm instructions, and guidance instructions based on the strategies returned by the countermeasure strategy module. The instruction issuance module sends the generated countermeasure instructions, alarm instructions, and guidance instructions to the data acquisition module. The data parsing module includes a target image parsing module and a target attribute data parsing module. The target image data parsing module parses the image information transmitted from the optoelectronic device, while the target attribute data parsing module parses the target attributes reported by the device, such as target flight longitude, latitude, altitude, speed, heading, target type, serial number (SN), and frequency. The data upload module stores the data in a database. The device guidance module guides the optoelectronic device after the radar detects a target, pointing the optoelectronic device's turntable towards the reported radar target location.

[0073] The data fusion module receives target data processed by the data processing module. This target data includes target radar data, target electro-optical data, and target radio data. The module fuses target radar data with target electro-optical data, and / or target radar data with target radio data, and / or target radar data, target radio data, and target electro-optical data. Radar data acquired through radar equipment provides information such as the target's longitude, latitude, altitude, speed, heading, and target type. Electro-optical data acquired through electro-optical equipment provides information such as the target's distance, azimuth, elevation, and target type (UAV, balloon, etc.), and further provides information such as the target's longitude, latitude, and altitude. Radio data acquired through radio equipment provides information such as the target's frequency, bandwidth, direction, serial number (SN), Media Access Control (MAC) address, longitude, latitude, and altitude. By fusing multiple types of information, target accuracy can be improved, target deduplication can be achieved, and the probability of target identification can be increased, thereby contributing to improved accuracy in reconnaissance and countermeasures.

[0074] The countermeasure strategy module receives target fused data or unfused target data obtained by the data fusion module, performs calculations, calculates the threat level of the target based on the user's countermeasure strategy information and the target's motion attributes, and formulates corresponding countermeasure strategies based on the status information of the countermeasure device, thereby accurately controlling the target.

[0075] The data storage module is used to store reported real-time target data, alarm information, countermeasure strategy information, system operation logs, daily intelligence information, and photoelectric and video data.

[0076] The low-speed, small-target reconnaissance and countermeasure system provided in this embodiment can efficiently detect threatening low-speed, small-target targets within the warning zone through joint reconnaissance by radar equipment, optoelectronic equipment, and radio equipment. By fusing radar data, optoelectronic data, and radio data, and generating countermeasure commands based on the fused data, it can automatically carry out countermeasures and improve the accuracy of countermeasures, thereby significantly enhancing the security of the warning zone.

[0077] use Figure 2The reconnaissance and countermeasure process of the low-slow-moving small target reconnaissance and countermeasure system can be as follows: Target detection is performed within the warning zone using a continuously operating radar. Detected targets, such as trees, flying objects, and vehicles, are initially screened. Suspicious low-slow-moving small targets, such as flying objects, are then targeted by other detection equipment, such as optoelectronic and radio equipment. Specifically, available detection equipment within the system is located, a route is planned, and then the route is sent to an autopilot. The autopilot transports the optoelectronic and radio equipment to a designated location. Upon arrival at the designated location, target location information is obtained from the radar, and the detection equipment points to the target (suspicious low-slow-moving small target). After various detection devices fuse target attributes, precise target information is obtained. If the target is a non-whitelisted drone or a balloon, or other high-risk target, countermeasure equipment is dispatched. Similar to the dispatch of detection equipment, the countermeasure equipment is dispatched via an autopilot. Once the countermeasure equipment reaches the designated location, it uses laser countermeasures, forces the drone to land, or performs navigation deception operations to achieve countermeasures, depending on the countermeasure strategy.
