A Single-point Passive Location Algorithm of Fixed Emitter Using Direction of Arrival and Its Rate of Change

摘要

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 scout, and comparison with the location algorithm only using direction of arrival is also given according to simulation results.
