摘　　要：文中针对被动声定位时风速的影响,分别对等效传播距离、风速和风向对声程差的影响、风对定角的影响及其修正开展了理论建模和仿真研究,仿真结果表明,采用修正后,5级风力下的定向精度影响小于0.3°。Aimed at the influence of wind speed at passive acoustic location, theory modeling and simulating research are developed for equivalent transmission distance, acoustic distance difference influenced by wind speed, wind direction and angle ascertaining influence by wind and its correction in the paper. The influence of direction ascertaining precision is less than 0.3° under the condition of 5 level wind power after correction by simulation.
