摘　　要：矢量水听器相比于声压水听器不仅可以进行左右舷侧分辨,还可以拥有更高的阵增益。并且其自身的声压传感器与振速传感器进行指向性组合还可以形成心形指向性,抑制特定方向的信号。根据实际情况,基阵安装存在不等间距布阵的可能。如果直接对各阵元信号进行波束形成则会产生旁瓣干扰。针对这种情况,论文提出一种基于单目标的虚拟阵元算法。通过该算法将不等间距阵列填补为等间距形式,来达到压低旁瓣的目的。Compared with the sound pressure hydrophone,the vector hydrophone can not only carry out the starboard and starboard resolution,but also has a higher array gain. Moreover,the directional combination of its own sound pressure sensor and vibration velocity sensor can also form heart-shaped directivity to suppress signals in specific directions. According to the actual situation,there is the possibility of unequal spacing in the array installation. If beamforming is performed directly on each array signal,sidelobe interference will be generated. In this paper,a virtual array algorithm based on single object is proposed. In this algorithm,the array with unequal spacing is filled with equal spacing to achieve the purpose of lowering the sidelobe.
