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

針對搭載矢量水聽器陣的水下機(jī)動小平臺，抑制自噪聲的方法主要有兩類：一類是通過物理技術(shù)控制自噪聲傳播，如采用特殊材質(zhì)保護(hù)水聽器；另一類是進(jìn)行信號預(yù)處理，如用矩陣濾波器通過空域濾波消除不感興趣的方位信息或噪聲源信息。（剩余3811字）
