摘　　要：副瓣对消技术是雷达抗有源压制式噪声干扰的一项重要措施，可以有效提高干扰环境下雷达最大探测距离。文中通过介绍副瓣对消的工作原理，从辅助天线设计、对消样本选取、主辅通道一致性三个方面分析副瓣对消的关键技术，结合抗干扰试验的常见问题，给出时序对齐、全量程噪声分段采样等解决方法，并分析现有副瓣对消性能指标的局限性，提出新的副瓣对消性能指标，并对指标的合理性进行了验证。The sidelobe cancellation（ SLC ） technology is an important measure of radar anti-active pressure noise jamming, which can effectively improve the maximum detection distance of radar. In this paper, start with the introduction of the working principle of SLC, analyses the main technologies from three aspects ： the design of auxiliary antenna, the selection of cancellation sample and the consistency of main-auxiliary channel. Combined with the common problems of anti-jamming experiment,the solutions such as time sequence alignment and full range noise segmentation sampling are given, and the limitations of existing sidelobe cancellation performance indicators are analyzed. At last, the paper proposes new sidelobe cancellation performance indicators, and the rationality of the indexes are verified.
