Abstract

In order to improve the anti interference ability to multi interference decoy of cross-shaped detector array against the weakness of identification width and identification amplitude methods, an anti interference method based on prediction and adaptive gate technology was proposed. According to the motion trail of the target, the motion models were built, the Kalman filter was used to predict the next time position and transform the coordinates to the image plane. Then the gate technology was used to search the pulse of the target until the target and the interferences were separated. A lot of tests show that the method has good performance on anti inference.

Key words： cross-shaped detector; adaptive gate; anti-interference; Kalman filter
