Analysis on horizontal distribution characteristic of underwater radiated noise of a small surface target

在单一平面水平等声压分布噪声模型及分析方法的基础上,给出一种以水平直线阵为数据获取湿端的舰船目标噪声水平空间分布特性的数学模型。据此对一种小型水面船舶的辐射噪声水平空间分布特性开展海上实测研究,并分析该类目标在水下产生的辐射噪声的频谱及水平空间分布特性。

In this paper, the measurement and analysis method for horizontal spatial characteristic of underwater radiated noise of vessel targets is researched thoroughly, and a underwater radiated noise spatial distribution modeling and analyzing method for equivalent sound pressure in single plane based on linear array measurement technology are put forward by the numbers. And the spatial characteristic of underwater radiated noise originated from a small surface ship target is measured on the sea, and its horizontal distribution characteristic of underwater radiated noise is investigated and analyzed in detail based on aforementioned underwater radiated noise spatial distribution modeling and analyzing method for equivalent sound pressure in single plane.
