摘　　要：针对多径效应使主动防护雷达探测精度降低的问题,提出了一种多径效应抑制方法。该方法结合传统多径效应抑制方法,并利用基于分组选择的数据处理算法,将受多径效应影响的俯仰角野值剔除、真值保留。实测数据表明,该方法在多种试验场地环境下均有效地抑制了多径效应的影响,提高了主动防护雷达的俯仰角测角精度。Multipath effect can worsen detection accuracy of active protection radars.This paper presents a method of multipath effect suppression,which combines the traditional method of multipath effect suppression and a data processing algorithm based on group selection.With the data processing algorithm,outliers in elevation caused by the multipath effect are removed and true elevation values are retained.Test results show that the proposed suppression method effectively suppressed the multipath effect and improved the elevation measurement accuracy of active protection radars in various test environments.
