摘　　要：自适应旁瓣对消(A SLC)是雷达抗有源干扰的有效方法。它采用空间滤波技术,通过辅助接收通道在干扰方向形成波束图的零点,实现对干扰信号的抑制。本文介绍了自适应旁瓣对消的原理,然后给出了基于DSP的A SLC实现方案,分析了自适应旁瓣对消的性能。同传统的对消系统相比,该系统具有更好的抗干扰性能。Adaptive sidelobe canceling pattern null in the direction of jamming suppress the jamming. The basic principle then, a hardware realization based on DSP （ASLC） is an effective measure against active jamming. Beam is formed by space filtering and assisted receive channels to of adaptive sidelobe canceling is introduced in this paper. And is given. Compared with traditional sidelobe canceling system. this system has better performances of ECCM.
