摘　　要：旁瓣对消技术是现代雷达抗有源干扰的有效方法。在理想条件下,旁瓣对消系统可以有效抑制干扰并保留期望信号,因此在现代雷达战场上得到了广泛应用。文章提出了5种关于针对旁瓣对消的建模方法,分别是开环算法、闭环算法、广义内积法、自适应剩余功率检测法和阻塞矩阵法,并针对不同来波方向和不同噪声的干扰进行了仿真验证。Side lobe cancellation technology is an effective method for modern radar to resist active interference.Under ideal conditions,side lobe cancellation systems can effectively suppress interference and retain the desired signal,making them widely used in modern radar battlefields.This article proposes five modeling methods for side lobe cancellation,namely open-loop algorithm,closed-loop algorithm,generalized inner product method,adaptive residual power detection method,and blocking matrix method.Simulation verification was conducted for interference from different wave directions and different noises.
