一种快速抑制单脉冲雷达角闪烁的方法

Method to Fast Suppress Glint in Monopulse Radar

一种小窗口的快速中值滤波方法能够有效抑制比幅单脉冲末制导雷达角跟踪中的角闪烁。该方法根据比幅单脉冲雷达测角原理,在测角之后对测量结果以小窗口中值滤波的方式进行处理,最大程度上保留测角结果的细节信息又能够有效地抑制角闪烁,并且有较低的运算量。通过对仿真及实测数据的处理,表明该算法可以明显降低末制导雷达在接近目标时角闪烁的影响,有效提高雷达角跟踪精度。

The narrow window median filter is a method to fast suppress glint in amplitude-comparison monopulse radar. Based on the angular measurement theory of amplitude-comparison monopulse radar, the algorithm deals with the measurement results by using the narrow window median filter way. This method not only reserves the details of the measurement results maximumly but also suppresses the glint effectively. Moreover, the calculation load is small. Simulation data and real data indicate that the algorithm may suppress the glint influence when terminal guidance radar gets close to target and the precision of radar angle track is improved.
