摘　　要：基于某型雷达,详细的分析了干扰信号带宽对旁瓣对消系统(ASLC)输出对消增益的影响,针对利用延迟线技术解决这一问题的方法.对延迟线数目以及延迟线的延迟时间大小的选取进行了分析和讨论,得出了有意义的结论,计算机仿真结果证明该方法能够很好的提高存在宽带干扰时系统的对消增益。Based on a wideband radar,the bandwidth performance of the Adaptive Side-lobe Cancellation system is exam- ined.It is shown how the number of taps and the delay between taps affect the bandwidth performance of the radar,and how the performance improved of an array with two weights and one or two delay behind each assistant channel.Com- puter and analysis demonstrate that the method improve the Canceling-ratio in ASLC system greatly.

关 键 词：ASLC 相对带宽 对消增益
