The invention discloses a soft constraint-based defense method for an unmanned aerial vehicle group and related equipment, and the method comprises the steps: predicting a nominal trajectory of a single target unmanned aerial vehicle based on a Minimum Snap algorithm, and obtaining a nominal trajectory function; detecting the number of base stations near the target unmanned aerial vehicle, and judging whether to initiate a defense attack to the target unmanned aerial vehicle according to the number of the base stations; if the number of the detected base stations is two, a hidden trajectory equation on the x axis at the current moment is obtained according to the spatial positions of the double base stations and the target unmanned aerial vehicle; solving an attack trajectory function in space according to the nominal trajectory function and the hidden trajectory equation; and after obtaining position information according to the attack trajectory function, sending the position information to the target unmanned aerial vehicle to control the target unmanned aerial vehicle to move according to the position information. The position information is sent to the target unmanned aerial vehicle, so that the target unmanned aerial vehicle deviates from the nominal trajectory function, hidden attacks are initiated on the unmanned aerial vehicle, and the attack concealment is improved.
Description
technical field [0001] The invention relates to the technical field of defense engineering, in particular to a soft constraint-based defense method and related equipment for unmanned aerial vehicles. Background technique [0002] GPS spoofing and jamming are among the existing defenses against drone swarm attacks. GPS jamming: is a relatively simple technique that only involves generating an RF signal strong enough to drown out the GPS satellites' transmitted signals. The subject of the GPS jamming attack will immediately realize that something is wrong, as the system will not be able to produce geolocation results. The principle of GPS spoofing: instead of transmitting jamming signals, it transmits fake signals, which it imitates. GPS jamming is easy to be discovered by the enemy, which makes the enemy adopt anti-jamming strategies. GPS deception is easily resolved by carrying position sensors on the drone swarm, that is, shooting down the drone swarm through GPS spoofing ...
