基于声强向量法和声压梯度法的水中目标定向

DETERMINATION OF BEARINGS OF UNDERWATER OBJECTS BASED ON ACOUSTIC INTENSITY AND ACOUSTIC PRESSURE GRADIENT

本文论述了适合于水雷引信的基于声强向量法和声压梯度法对水中目标的特定部位 ,特别是辐射低频线谱分量的主机和辅机部位定向的方法 ,并对它们的定向原理以及在海洋环境噪声干扰场情况下的误差特性进行了分析。

A method based on acoustic intensity and acoustic pressure gradient is discussed and applied to determine the bearings of underwater objects, especially of main engines and auxiliary engines radiating low frequency line spectrum noise. Principles and errors of the two methods in the presence of ocean ambient noise are analyzed.
