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 |
