摘要

研究反舰导弹末制导雷达抗质心式箔条干扰的信号处理算法问题。分析了质心式箔条干扰的作用机理,以目标回波与箔条干扰在多普勒维的差异为切入点,设计了多MTI滤波器对回波进行滤波,最后利用Matlab软件进行仿真验证。仿真结果表明,参数设置合理的多MTI滤波器可有效改善箔条干扰下的信干比,提高反舰导弹抗质心式箔条干扰的性能。

Abstract

The paper is focused on signal processing algorithm used for anti-ship radar seeker to anti-centroid chaff jamming. The principle of centroid chaff jamming was analyzed. Then, according to the difference in the Doppler dimension between target and chaff jamming, the multiple MTI filter was designed. Finally, the result was validated by using the Matlab software. The simulation results indicate that the multiple MTI filter with reasonable parameters can meliorate the signal-to-interference ratio and improve the capability of the anti-ship missile countering centroid chaff jamming.

Key words： multiple MTI; centroid chaff jamming; MTI filter; anti-ship radar seeker
