A Multi-target Tracking Method Against Intelligent RGPO Jamming

In this paper, considering the serious defects of intelligent Range Gate Pull-off (iRGPO) jamming to the performance of the radar multi-target tracking, a novel multi-target method against iRGPO jamming is investigated. The problem of long-time stable target tracking against the iRGPO jamming is solved by proposing a multi-target data association algorithm based on backtracking. Firstly, the association probability between measurements and target is selected as the optimization function to construct the model. Next, a target tracking method based on backtracking is proposed to obtain the measurements of false targets, and then a filtering process is used to correct the trajectory further. Finally, simulation results are provided to verify the validity of the proposed algorithm.
