| 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).Becauseofthehigh nonlinear of TOA measurement equation, the observability matrix which is got by calculating Jacobin matrix is toocomplextoobtain explicit analysis conclusions. A linearization equation is deduced through a new idea, and the observabilityconditionsofSOPLAT using TOA and DOA measurements are obtained. Finally, a compute simulation result is presented. |
| Keywords: passive location observability time of arrival direction of arrival |
