摘要

为了削弱无源探测系统中存在的强噪声,提出了多路参考信号自适应噪声抵消算法。利用目标回波信号与噪声信号的传输通道差异性,通过对接收阵列各阵元接收信号求差得到多路参考信号。仿真结果表明,该算法可以有效抵消噪声,从而提高系统中弱信号的检测性能。

Abstract

To weaken the strong noise in passive detection system, multi-reference adaptive noise cancellation algorithm. By using the transmission channel diversity between target echo signal and noise, multi-reference signals are obtained through minus between the received signals of every receiving element. Simulation result shows that this algorithm can offset noise effectively, so that the weak signal detection performance is improved.

Key words： passive detection; weak signal detection; noise cancellation; improved algorithm
