一种单站无源定位方法及其可观测性分析

A New Single Observer Passive Location and Tracking Technology and Its Observability Analysis

利用非线性系统可观测性定理分析了径向加速度信息在目标运动分析(TMA)中的可观测性问题,得到径向加速度观测所能确定的目标状态参数及其需要满足的观测条件,从而证明一种联合径向加速度和角度信息的单站无源定位方法的可行性,并分析其可观测条件和可观测度。通过计算机仿真验证了讨论的结果。

The observability problem of the passive location system utilizing the radial acceleration information of the emitter is analyzed. It is proved that the range and speed information of the emitter can be determined from the radial acceleration under certain conditions, so a new target motion analytical technology using bearing and radial acceleration measures is deduced. The observability conditions for this technology are analyzed and verified with the computer simulation.
