在现代海战中 ,舰船大量使用无源箔条干扰。由于箔条云假目标漂移的速度和舰船运动速度相差不大 ,它对反舰导弹末制导雷达构成极大的威胁。本文利用舰船回波与箔条回波时域波形的区别 ,提出一种基于波形相似性和稳定性差异 ,通过构造平均相似值和峰距差两个波形特征随机变量 ,并分别取它们的样本均值和样本标准差作为识别特征的模式识别抗箔条实用新方法。外场试验考核和实验室仿真证明 ,该方法平均正确识别率达到 90 %以上 ,能满足实时性要求。
In modern naval battle, a large number of ships using passive chaff interference. Due to the drift speed of the chaff cloud false targets and the ship motion speed is not much difference, it poses a great threat to the anti-ship missile terminal guidance radar. In this paper, the difference between the ship echoes and the chaff echoes is proposed. Based on the similarities and differences in the stability of the waveforms, Sample Mean and Sample Standard Deviation as Pattern Recognition Anti-Chaff Practical Methods for Identifying Features. Field test and laboratory simulation test proved that the average correct recognition rate of more than 90%, to meet the real-time requirements.
