Description

Technical Field

[0001] This invention relates to the field of anti-drone technology, specifically to a drone deception location generation system, method, terminal, and medium. Background Technology

[0002] In recent years, drones have played a significant role in the Middle East battlefields. Their high mobility, low cost, lack of need for pilot safety considerations, and small size and strong concealment have been proven in actual combat, and their combat performance and advantages have been recognized by various countries. Given the large-scale deployment of drones on the battlefield, research into counter-drone technology has become increasingly important.

[0003] Currently, the main counter-drone technologies include: high-power jamming to suppress remote control links, firepower strikes, net-and-ball capture, radio hijacking, and drone guidance. The drawback of high-power jamming is its limited effectiveness against autonomously navigational drones; after being subjected to high-power jamming, the drone's flight path and crash site become uncontrollable, easily leading to secondary safety incidents. The drawback of firepower strikes is the high cost of precision-guided artillery shells, making them overkill for drones. Net-and-ball capture has extremely limited effective range, applicable only within visual range. Radio hijacking involves deciphering the drone's remote control link to seize control, but radio deciphering is difficult and lacks versatility. Drone guidance and deception primarily involve injecting time delays into genuine GPS navigation signals using jamming equipment, forwarding them to the target drone, causing it to receive incorrect positioning information, thus affecting its flight status and achieving the counter-attack objective. It possesses high stealth capabilities and is a relatively ideal counter-measure.

[0004] In drone jamming and deception, the time delay of injecting real GPS signals is determined by the position of the target drone, the deception point, the jamming equipment, and the GPS satellite position. The deception point is determined by the deceiving party, and its position determines the flight direction and trajectory of the target drone after being deceived. Therefore, in order to make the target drone fly to the deceived destination, the appropriate deception point position must be calculated in real time during the jamming process.

[0005] The inventors discovered that conventional relay-type drone navigation deception methods do not address how to lure and deceive the target drone to a deceptive destination. Therefore, this invention provides a drone deception location generation method, which provides a useful supplement to relay-type drone navigation deception methods. Summary of the Invention

[0017] S7. Based on the current location of the target drone, the decoy location, the GPS satellite location, and the jamming device location, calculate the forwarding delay of the GPS satellite signal and jam the target drone.

[0018] S8. The control center sends out a detection signal through the telemetry and control module to conduct telemetry. The target UAV position is detected at the set time interval. S6 to S8 are repeated to calculate the decoy position and the corresponding time delay in real time.
