摘要

针对四元正交探测器鉴宽、鉴幅等抗干扰方法对抗多个红外诱饵干扰能力弱的缺点,提出一种基于预测和自适应波门相结合的抗干扰方法。根据目标的运动轨迹建立运动模型,利用Kalman滤波预测目标下一时刻位置并通过坐标转换到像平面上,以此位置作为自适应波门的中心位置并扩大搜索范围,使目标脉冲进入波门直至目标与干扰分离。大量试验表明,该方法对抗多个红外干扰的效果显著。

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
