无源多基地雷达中一种综合航迹处理方法

Integrated Track Management Method in Passive Multi-Static Radar

本文对基于调频广播信号的无源多基地雷达系统中的目标跟踪问题进行了研究,提出了一种综合航迹处理方法.本文将航迹划分为四种状态,即起始航迹,试验航迹,确认航迹,以及消亡航迹,详细介绍了每一种航迹的处理方式.本文顺序地利用每个接收-发射对的观测量来更新航迹,以减小算法复杂度.仿真实验与实测数据结果证明了本文算法的有效性.

The paper investigates the target tracking problem arising in FM signal based passive multi-static radar, and proposes an integrated track management method. We divide the tracks into four statuses, i. e. initial track, tentative track, confirmed track, and deleted track. Tracking methods for each kind of tracks are detailed. We sequentially exploit measure- ments of each receiver-transmitter pair to update the tracks, causing the rapid reduction of the computation complexity. Simu- lation and the real life data results demonstrate the effectiveness of the proposed method.
