一种新的双复权雷达干扰自动对消系统研究

A new double-complex number weight radar jamming automatism counteracted system

复杂电磁干扰环境下,雷达干扰对消系统性能发挥受到了挑战。针对对消系统面临的这一问题,分析了干扰对消的基本原理,并对影响对消性能的主要因素进行了深入探讨。在此基础上,设计了单延迟节FIR滤波器双复权对消系统,大大减小了空间波程差和通道不一致性对对消系统造成的不良影响。仿真结果验证了系统的有效性。

Under the complicated electromagnetic jamming condition, the radar jamming counteracted system capability is limited. By this problem of the counteracted system,the keystone on jamming counteraction is analyzed and the primary factors which affect the counteracted capability are discussed. On this base, the odddelay FIR filter double-complex number weight counteracted system is designed, which deduces the bad infection on the counteracted system caused by the space wave distance difference sum-passage＇s not coherence. The simulated result validates validity of the system.
