研究矢量均匀线列阵波束形成算法的左右舷分辨性能。水听器可同步共点地测量声场的声压和质点振速,为一具有指向性的空间共点阵,从而能够解决单线阵声呐的目标左右舷模糊问题。文章分析了采用不同波束形成方法时矢量阵广义Cardiod处理和声强处理的目标左右舷分辨性能,并利用海试数据进行了验证。研究结果表明:自适应波束形成具有比常规波束形成更佳的左/右舷分辨性能,且对矢量阵处理而言,广义Cardioid处理更为稳健和实用。
The port / starboard discrimination performance of vector uniform linear array beamforming algorithm is studied. The hydrophone can simultaneously measure the sound pressure and the particle velocity of the sound field in a synchronized manner, which is a co-space lattice with directivity and can solve the target port-starboard ambiguity problem of the single-line sonar. In this paper, the target port-to-starboard discrimination performance of generalized Cardiod processing and acoustic intensity processing of vector array using different beamforming methods is analyzed and verified by sea-test data. The results show that adaptive beamforming has better left / starboard resolution than conventional beamforming, and the generalized Cardioid processing is more robust and practical for vector array processing.
