ABSTRACT:
A passive emitter location system is capable of performing emitter location autonomously from a single airborne observation platform and includes a bearing measurement system, a system for measuring doppler induced frequency shifts, and means for estimating the emitter location based on non-simultaneous measurement of the bearing and frequency using extended Kalman filters preferably initialized by a single measurement delayed initialization procedure.
