【摘要】 单水听器声源定位技术是近些年来水声领域的研究热点。本文在利用Warping变换及逆变换分离、还原简正波的基础上,提出一种单水听器声源被动定位方法。对分离的任意两阶简正波共轭相乘,采用相位补偿和距离匹配相结合的方法进行声源测距。根据深度函数在深度上的分布规律,用正弦函数对声源深度进行估计。本文的仿真实验数据的处理结果验证了提出的定位方法,可以较准确地对浅海水下定声源进行定位。
【Abstract】 In recent years, the acoustic source location technology of single hydrophone is a research hotspot in the field of underwater acoustics. In this paper, a passive localization method of single hydrophone is proposed based on warping transform and inverse transform to separate and restore normal wave. The method of phase compensation and distance matching is used to measure the sound source by the conjugate multiplication of any two order normal waves. According to the distribution law of depth function, the depth of sound source is estimated by sine function.The simulation data processing results in this paper verify that the proposed method can accurately locate the fixed sound source in shallow water.
【Key words】 single hydrophone; sound-source location; normal mode separation; phase compensation; depth function;
