Abstract: Aiming at the flight task optimization problem of unmanned aerial vehicle (UAV) when multi-UAVs deceive the track of netted radar, a multi-UAV cooperative track deception jamming technology based on swarm intelligence algorithm is proposed. Firstly, the mathematical model, constraint conditions and optimization function of multi-UAV cooperative track deception of netted radar track are given. Secondly, three typical swarm intelligence algorithms are used to optimize the multi-UAV cooperative track deception model. Finally, the differences of three swarm intelligence algorithms in optimizing the multi-UAV cooperative track deception model are compared through simulation experiments.
