摘要
Abstract
In applications,a vector hydrophone array could triple or quadruple the number of channels which dramatically increased cost,computational complexity and sample support requirement.To mix vector hydrophones with pressure hydrophones was an effective method.Five representative configurations of mixed hydrophone arrays were studied.In Gauss noise circumference,the models＇ direction-of-arrival（DOA） was analyzed through MUSIC algorithm.Different SNR and one target movement brought out vary effects to DOA.Computer simulation results showed that alternate configuration was superior to center configuration if there were the same number of acoustic vector hydrophones;the vector hydrophone was disposed at the middle of the array was relatively reasonable to be disposed at the center.关键词
