Target trajectory detection of multi-UAVs based on arrival time

Abstract

Improving the survival probability of important ground facilities requires setting protective measures above ground with the development of precision guided weapons. For low altitude protection, a suitable detection system for a given velocity of target is a must. A special detection system fulfilling the requirements for protection was constructed based on multiUAVs coupled with radar device to track the coming target in this work. The target’s motion model was built as a function of signal arrival time, which was obtained from the objective function. To achieve better stability and tracking performance., an optimization method was presented according to the arrangement of detection system and parameters of the target, by minimizing the bias between the system centre and target position. It was found that effective tracking was achieved for the non-cooperative target with following control taken into consideration.
