摘　　要：声场声压与振速的相干性是声压、振速信息联合处理的重要物理基础之一 ,本文对其进行了初步的分析 .在新型组合传感器湖试的基础上 ,把环境噪声场分解为不相干的各向同性分量和相干的各向异性分量 ,初步分析环境噪声场的构成 ;The coherence analysis of the sound field using prssure and particle velocity combined processing was discussed.A new kind of combined sensor was used to gather the information of the sound field.The main idea of this paper is to seperate ambient noise field,and the characteristics of it can be further studied.The coherence of a point source sound field was also analyzed to verify the validity of the approach.

关 键 词：声压 振速 声场 环境噪声 水下噪声
