The technology of onboard passive detection and location is an important research field of airborne Electronic Counter Measures(ECM).A 3-dimensional model is set up for passive locating of the maneuvering targets in space by single airborne observer.Based on traditional methods for measuring the change rate of phase difference,Doppler and its change rate information are added.The locating principle is discussed,and the formulae for location are re-deduced.The pre-processing and system state equations are presented.A Unscented Kalman Filter(UKF) approach for white noise model with adjustable level is proposed to improve the locating and tracking accuracy.With the help of computer simulation,the method is proved to be correct and effective.
