摘　　要：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 vector information of the acoustic measured by the particle velocity sensors, and this field which contains the bearing of the source can be makes it possible for the vector hydrophone linear array （VHLA） sonars to have the ability of solving the notorious port/starboard ambiguity suffered by the scalar single-line an＇ay. In this paper, two beamformers based on the generalized cardioid processing （GCP） and the sound intensity processing （SIP） are analyzed theoretically to explore the performance of port/starboard discrimination, and the results are compared to the experimental data obtained in sea trials. Analysis shows that the adaptive beamformer outperforms the convectional one. Furthermore, with respect to the ability of signal detection, GCP is a better one for the VHLA signal processing.
