| 摘 要： | 单站无源定位跟踪技术中,可观测性分析是一个关键问题,但是由于TOA测量方程的非线性程度太高,直接通过计算Jacobin矩阵得到的可观测矩阵形式非常复杂,很难得出明确的分析结果。采用新的思路推导了一种TOA测量方程的线性化方程,分析了测量TOA和DOA单站无源定位的可观测条件。最后给出了计算机仿真结果。

| Abstract: | The observability analysis is a key problem of SOPLAT (single observer passive location and tracking). (Because) (of) (the) (high) nonlinear of TOA measurement equation, the observability matrix which is got by calculating Jacobin matrix is too (complex) (to) (obtain) explicit analysis conclusions. A linearization equation is deduced through a new idea, and the observability (conditions) (of) (SOPLAT) using TOA and DOA measurements are obtained. Finally, a compute simulation result is presented. |
