ABSTRACT:
Method and apparatus for passive emitter location which overcomes the time to range and other restrictive limitations of passive tracking systems by combining pulse frequency, time of arrival and bearing or angle of arrival measurements to obtain a range measurement at each parameter update. No specific observer motion is required and relatively few restrictions on emitter motion are present in order to obtain an accurate determination.
