  • For the issue of location ambiguity of high PRF(Pulse Repetition Frequency) signal in three satellites TDOA (Time Difference Of Arrival) passive location system, a new method based on direction information acquired by adding interferometer on main satellite is presented in this paper. Considering ambiguity may occur in direction finding with interferometer, a method is proposed to eliminate location ambiguity by using ambiguous direction information, which is also practicable without ambiguity in direction finding. Firstly, the distance parameter defined in this method of every location is computed, and then false locations are eliminated by threshold detection. This method is able to reduce the number of ambiguous locations, and improve location ambiguity effectively.
