For target tracking with passive detection just gets the angle value

the passive detection system is studied by computer simulation

including the effect caused by different fighter maneuver manners.A localization model of passive detection is built under the modified polar coordinates.The filtering characteristics of extended Kalman filter of the model and fighter maneuver manners which effect on the model are analyzed.The tracking model is studied by the computer simulation with Matlab.The results show that the passive detection of target tracking algorithms could not track the target in the case of non-maneuver;the algorithms would be re-divergent in the case of non-maneuver after a certain period of maneuver;the target is tracked unless the fighter aircraft maneuver appropriately.
