Abstract： This paper investigates the design method of spatial domain matrix flters under near-field conditions， aiming to suppressplatform self-noise interference and improve target detectionaccuracySpatialfilteringof the signal is achieved through pseudoinverse criteriaand two optimization criteria.Simulationand experimentaldata analysis show that the matrix filter designed based on the platform self-noise zero-response constraint criterion exhibits superior performance in suppressing self-noise interference of the output signal.

Keywords：spatial filtering;platformself-noise; interference suppression

针对搭载矢量水听器阵的水下机动小平台，抑制自噪声的方法主要有两类：一类是通过物理技术控制自噪声传播，如采用特殊材质保护水听器；另一类是进行信号预处理，如用矩阵滤波器通过空域滤波消除不感兴趣的方位信息或噪声源信息。（剩余3811字）
