无源侦察中高速目标轨迹跟踪研究

Research on high-speed target tracking in a passive reconnaissance system

导弹和卫星等高速目标的跟踪是反导雷达系统中的核心问题。传统的轨迹跟踪方法不能很好适应无源侦察设备对于高速目标的跟踪。本文提出了一种高速目标纯角度轨迹跟踪方法。该方法在初始跟踪段使用平均加权方式,并在一定迭代次数后采用Singer滤波,有效地降低了整个跟踪阶段的均方根误差,取得较好效果。

Tracking high-speed targets such as missiles and satellites is the core issue in the antimissile radar system. The conventional methods cannot satisfy the requirements of the passive reconnaissance system for the high-speed target tracking. A high-speed angle-only target tracking method is presented. The average weighting method is adopted in the initial period,and then the Singer filter is used after some iterative steps,which can effectively reduce the RMS error of the whole tracking process and obtain good results.
