| 摘 要： | 可观测性分析是无源定位与跟踪系统的前提和基础。由于卫星运动系统方程是状态变量的隐函数形式，以及观测方程的非线性，使得对卫星目标仅测角无源定位的可观测性研究难度较大。鉴于此，从伪线性化角度对非线性系统方程进行改造，推导了关于状态变量的显性系统状态方程，对仅测角条件下的单星对星无源定位系统进行了可观测性分析，为进一步研究仅测角单星对星的无源定轨跟踪提供了理论基础。最后给出了仿真实例，验证了理论分析的正确性。

| Abstract: | Observability analysis is the basis and prime task in a passive location and tracking system.The observability analysis of bearings-only passive location for a satellite target is a complicated problem,for the system motion equation of the satellite is an implicit function of system state and the observation equations are nonlinear.In this article,the nonlinear equations of the bearings-only spaceborne single observer passive location system are pseudolinearized,and the system motion equation is transformed... |
