The monostatic passive location system is actually a bistatic radar system which employs a FM broadcast transmitter as the illuminator,and its radar receiver is located on another place.In the practical radar system based on external illuminator,the azimuth angle can be acquired using digital beam formation technique and the angle measuration by comparing amplitude.According to Time Difference of Arrival(TDOA),the distance between the target and the radar station is achievable.Thus an applicable passive location algorithm of moving target based on single fixed-site illuminator is available.Finally,the computer simulation results are presented,and good results has been achieved in engineering by this method.
