摘　　要：简要介绍了自适应旁瓣对消的基本原理。重点研究了自适应旁瓣对消在机载脉冲多普勒雷达中的工程实现方法,该方法打破了自适应旁瓣对消目前只能应用于采用低重脉冲重复周期的脉冲多普勒雷达的限制。通过对自适应旁瓣对消结果的分析,表明该方法完全能够满足现有机载脉冲多普勒雷达抗有源旁瓣干扰的需求。This article briefly introduces basic principle of adaptive sidelobe cancellation and focuses on the research of one adaptive sidelobe cancellation engineering method of the airborne pulse doppler radar. This method breaks the limitation which is that adaptive sidelobe cancellation currently can only be applied to the pulse doppler radar with low pulse repetition interval. The analysis of adaptive sidelobe cancellation results shows that this method can completely meet the needs of the existing airborne pulse doppler radar against active sidelobe jamming.
