摘  要：對(duì)時(shí)差定位體制下的多站無(wú)源定位跟蹤系統(tǒng)的可觀(guān)測(cè)性進(jìn)行分析。先在理想測(cè)量模式下，使用代數(shù)方程唯一解對(duì)可觀(guān)測(cè)問(wèn)題進(jìn)行分析，得到多觀(guān)測(cè)器條件下目標(biāo)可觀(guān)的最少觀(guān)測(cè)器數(shù)目;另外，考慮實(shí)際系統(tǒng)的傳感器和導(dǎo)航設(shè)備測(cè)量誤差，給出了目標(biāo)不可觀(guān)測(cè)時(shí)的多觀(guān)測(cè)器運(yùn)動(dòng)方程約束。

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
