摘　　要：在现有单站无源定位技术的基础上,介绍了新的基于机动辐射源目标的DOA和TOA测量信息的单站无源定位的可观测性分析。此分析直接应用非线性系统的可观测性分析原理,得到了基于DOA和TOA测量信息的单站无源定位的可观测性条件,并对其进行了计算机仿真。与文献[1-2]相比,此可观测性分析更直观更简明。On the basis of the existed single - observer passive locating technologies, we introduced a new observability analysis method of the locating and tracking based on Direction of Arrival（DOA） and Time of Arrival （TOA） Measurements of maneuvering targets. The observability analysis adopted directly the observability analysis principle of non - linear system, and educed observability conditions of the single observer passive locating and tracking based on DOA and TOA Measurements. We also carried out computer simulations. Compared with the methods presented in the literature I and literature 2, the observability analysis is more directly and compactly.
