脉冲压缩距离副瓣抑制研究

Research on suppression of pulse compression range sidelobes

针对固态雷达脉冲压缩距离副瓣淹没弱小信号,进而影响目标显示与检测的问题,提出一种设计最小化ISL失配滤波器结合距离副瓣自适应抑制算法。在对脉冲压缩系数优化的情况下,利用脉冲压缩先验信息,识别脉压副瓣区域,降低强目标副瓣对周围目标的检测影响,并通过仿真试验验证了方法的可行性和有效性。

In view of the problem that weak signals are submerged by the pulse compression range sidelobes of the solid-state radar and target display and detection are affected,an adaptive suppression algorithm is proposed by combining the minimal ISL mismatch filter with range sidelobes.In the case of optimizing the pulse compression coefficient,the prior information of pulse compression is used to identify and suppress the range sidelobes and reduce the impact of strong target range sidelobs on the detection of surrounding targets.The method proves to be feasible and effective through the simulation test.
