Abstract：The multi-unmanned aerial vehicles (UAV) have the advantages of strong robustness, high detection accuracy, and high mission efficiency in the cooperative tracking of ground-moving targets, and therefore have significant research impacts. To solve the limitations of sensor information, how to use as little target state information to effectively achieve stable tracking of targets has become one of the critical problems where fixed-wing UAVs shall achieve fixed-range hover tracking. Based on tracking stability, a multi-UAV cooperative guidance law with an equal phase difference between neighbouring aircraft was designed to solve the problem of multi-UAV cooperative target tracking. It was generated by combining the two laws to form a multi-UAV cooperative target tracking and guidance law. Finally, the experimental simulation results of tracking variable-speed moving targets have verified the effectiveness and feasibility of the scheme, which is critical to the cooperative target tracking of multi-UAV.
