摘　　要：针对近距离舰船目标回信号经相参积累处理后,舰船目标跨越多个多普勒单元,使用区域平均加权方法解算角误差;为进一步提高角闪烁的抑制效果,对测角结果以小窗口中值加权滤波的方式进行处理,既保留测角结果的细节信息又有效抑制角闪烁。通过实测数据的处理,表明该算法可以明显降低末制导雷达在接近目标时角闪烁的影响,有效提高雷达角跟踪精度。For ship target echo from close range after coherent integration processing,ship targets extend to several Doppler units,the weighted average method to solve errors is used.In angular measurements with a small window in the value-weighted fil⁃tering,maximum angle measurement result details are retained and can effectively curb the glint.Real data indicate that the method may suppress the glint influence when guidance radar gets close to target and the precision of radar angle track is improved.
