Abstract: Passive location and tracking of moving target in space is a key problem in recent years.The technology has been widely applied in the fields of aviation and guidance.It has expansive prospects for application. The modified gain EKF (MGEKF）algorithm for passive localization of maneuvering target by single station is discussed.Based on the time difference of arrival (TDOA) and the direction of arrival (DOA) of the emitter,passive localization by single station is practicable,and also the localization of maneuvering target is practicable with the MGEKF algorithm.Some concerned issues,such as technical problems,principle and algorithem are discussed in this paper.With the help of computer simulation,the method is proven to be correct and effective.

Key words: single station passive location, MGEKF, azimuth angle, elevation angle, azimuth angle changing rate
