摘　　要：由于近海水面舰船较多,形成较强干扰,不利于对水下目标尤其是水下弱目标的探测发现,本文针对水平阵,基于最小二乘原理,设计了近场宽度距离深度域矩阵滤波器,使其能够抑制水面干扰,有效探测水下弱目标,并对宽带距离深度域矩阵滤波器与窄带距离深度域矩阵滤波器的滤波效果进行分析对比。Due to the large numbers of ships on the offshore surface, strong interference is not conductive to the detection of underwater targets, especially the weak underwater targets. The near field wide band distance-depth domain matrix filter is designed in this paper, which is based on the principle of least square and HLA, It aims to suppress surface interferences and detect underwater targets effectively, The filter effect of the wide band distance-depth domain matrix filter and the narrow band distanc-depth domain matrix filter is analyzed and compared.
