Target location for passive radar in single frequency network

A target detection model for DTTB-based passive radar in a single frequency network (SFN) is established. Also, the distinctive difficulties of the SFN passive radar is analyzed, and the target location algorithm based on the track mapping and the track association to eliminate the location ambiguity caused by many transmitters of the SFN passive radar is proposed. A SFN passive radar composed by three transmitters and one receiver is used to verify the algorithm. The simulation results show that the algorithm can eliminate the location ambiguity and increase the location accuracy effectively.
