Patent ID: 7535420

Claim:
A method for determining a geolocation and a velocity of a moving non-cooperative target, the method comprising: acquiring with a first collector a first signal measurement corresponding to a signal emitted from an emitter on the target, the first collector being capable of acquiring each and every one of a first angle of arrival signal measurement, a first direction of arrival signal measurement, a first target range signal measurement, a first position signal measurement, and a first velocity signal measurement; forming a first measurement matrix utilizing the first acquired signal measurement; applying the measurement matrix to a recursive filter; acquiring with a second collector a second signal measurement corresponding to a signal emitted from the emitter on the target, the second collector being capable of acquiring each and every one of a second angle of arrival signal measurement, a second direction of arrival signal measurement, a second target range signal measurement, a second position signal measurement, and a second velocity signal measurement; forming a second measurement matrix utilizing the second acquired signal measurement; and applying the second measurement matrix to the recursive filter to determine the geolocation and the velocity of the target without receiving or requiring a precise location or orientation of the target from a communication transmitted from the target.
