Abstract:

To solve the problem of low detection probability and high clutter rate in target tracking for noncooperative bistatic radar, an improved probability hypothesis density filter is proposed in this paper. Firstly, a new method of track identification and state estimation is proposed. Secondly, the survival probability is defined as a variable related to the target state. Thirdly, whether each candidate target is measured at each time is recorded, and real target and false target caused by clutter are distinguished using sequential probability ratio test. Finally, the target state is estimated offline. Simulation experiment results indicate that the proposed algorithm significantly improves the performance of target tracking for noncooperative bistatic radar, and can deal with the problem of low detection probability and high clutter rate effectively.

Key words: noncooperative bistatic radar, target tracking, improved probability hypothesis density filter, sequential probability ratio test
