摘　　要：雷达回波信号的相关性给信号分析带来了诸多不便,因此对于信号的预处理变得极为重要。介绍了一种信号预白化处理的方法,通过提取独立分量对信号进行去相关。Matlab仿真表明此方法在信号处理中起到了很好的去相关作用,为信号的后续处理消除了部分冗余信息,确保了雷达系统信号处理实时性的要求。The correlativity of radar echo signals bring quite a lot of troubles to signal analysis, so the signal pretreatment becomes very important. This paper introduces a method of signal prewhit- ening processing,the signal is decorrelated by extracting independent components. Matlab simula- tion indicates that the method takes good effect on decorrelation in the signal processing, which e- liminates partial redundancy information for the follow-up signal processing, ensures the real-time requirement to signal processing of radar system.
