摘  要:对时差定位体制下的多站无源定位跟踪系统的可观测性进行分析。先在理想测量模式下,使用代数方程唯一解对可观测问题进行分析,得到多观测器条件下目标可观的最少观测器数目;另外,考虑实际系统的传感器和导航设备测量误差,给出了目标不可观测时的多观测器运动方程约束。

Abstract: The observability of multi-station passive location and tracking system under time difference location system is analyzed. Firstly, in the ideal measurement mode, the observable problem is analyzed by using the unique solution of algebraic equation, and the minimum number of observable observers under the condition of multiple observers is obtained. in addition, the measurement errors of sensors and navigation equipment in the actual system are considered and the motion equation constraint of multi-observer is given in case of the unobservability of the target.

Keywords: multi-station passive location; time difference location; observability

在无源定位跟踪系统中,可观测性分析已经成为一个重要的研究内容,是实现无源定位跟踪的前提,只有当目标状态完全可观测时,定位跟踪问题才有唯一可靠的解[1-2]。(剩余2778字)
