摘　　要：角闪烁是雷达目标的固有特性,特别是在近距制导时,角闪烁是影响比例制导雷达导引头视线角速度精度的主要因素之一,可能使脱靶量增加,甚至导致目标丢失。本文针地面和海面目标分别提出了相应角闪烁抑制算法,来提高导引头末端视线角速度精度,并利用地面跑车实测数据验证了算法的有效性。Angular glint is an intrinsic characteristic of radar target,which is one factor of major influencing millimeter wave guidance radar angular tracking accuracy especially in short range guidance,may make miss distance increase,even leads to target lost.Aiming at ground target or sea-surface target,algorithm to suppress corresponding angular glint is presented respectively,and validity of presented algorithm is verified by measured data of ground roadster.
