摘　　要：在对浅海近程噪声源定位研究时,针对多途环境和左右舷模糊问题,采用了组合阵与时反技术相结合的方法。利用矢量水听器的单边指向性去除虚假声源的干扰,并利用时间反转镜技术抑制多途效应的影响,从而实现了浅海近程声源定位。In the study of localization in shallow sea noise source, beause of the problem of port and starboard ambiguity and the muhipath environment, the combinatory array and time reversal mirro technology are adopted. Using the unilateral directivity of the vector hydrophone removes the false source, Using the time reversal mirror technology restrains the influence of the muhipath effect, thus the position of sound source in shallow sea can be located.
