摘　　要：雷达距离 /时间旁瓣抑制滤波器的设计通常以旁瓣电平最低为设计目标 ,未考虑增益处理损失的控制 ,在某些情况下会导致输出信噪比损失过大 ,影响弱信号的检测 .本文研究增益处理损失任意给定条件下的旁瓣抑制滤波器的设计 。Radar range/time sidelobe suppression filters are usually designed only to reduce the sidelobe to the level as low as possible, and the loss in process gain (LPG) is not specially considered. In some cases the LPG is large enough to influence the detection of weak signals. The sidelobe suppression filters with LPG arbitrarily given are proposed, and the design approach of optimal integrated sidelobe level filter and optimal peak sidelobe level filter both with constant LPG is given.
