摘　　要：矢量水听器的良好性能使得它可以在获取声压信息的同时获取振速信息,具有心型指向性,而且由矢量水听器构成的线阵,具有良好的判断所探测的目标位于阵的左舷或者右舷的性能。在矢量拖曳线列阵信号处理过程中,最小方差无畸变响应(MVDR)的波束形成技术相比于常规波束形成技术具有主瓣宽度更窄,旁瓣更低的优势,可以提高目标方位分辨力。The vector hydrophone can obtain the information of sound pressure and vibration velocity at the same time,and it has the directivity of heart shape.The linear array composed of vector hydrophones has a good performance in judging that the detect⁃ed target is located on the port or starboard side of the array.In the process of vector towed line array signal processing,the mini⁃mum variance distortion-free response(MVDR)beamforming technology has the advantages of narrower main lobe width and lower side lobe compared with conventional beamforming technology,which can improve the target azimuth resolution.
