摘　　要：提出了一种利用波达方向角(包括方位角与俯仰角)及其变化率信息对固定辐射源进行单站无源定位的算法,对可观测性条件与定位误差的影响因素进行了分析,并将融入波达方向角变化率信息的EKF算法用于载机在航迹上的多次测量定位,并通过仿真将该算法与只测角定位算法进行了比较。In this paper, a single-point passive location algorithm of fixed emitter using direction of arrival （including azimuth and elevation） and its rate of change is put forward, and conditions of observability and influencing factors locating error are analyzed. The EKF algorithm combined with change rate of direction of arrival is used in location by measuring multi-point along with tracks of the scout, and comparison with the location algorithm only using direction of arrival is also given according to simulation results.
