摘要/Abstract

摘要： 为了实现浅海目标声源深度及多途条件下虚源深度的测量，通过分析理想信道与多途信道下聚焦波束形成声图法在源深度测量方面的机理，提出噪声源正横时能量最大深度测量法，并根据多途条件下声源真实位置与虚源位置的对称关系，实现水平直线阵布放深度的测量。文中利用理论仿真与实验数据相结合的方法，分析了不同条件下目标声源深度测量的准确性，并给出了目标声源精确定位结果。

Abstract: In order to measure the depths of the objective sound source in shallow water and virtual sound sources under multi-path conditions, an abeam energy maximum measurement method was proposed by analyzing underwater image mechanism in depth measurement under the ideal and multi-path conditions. It can also realize the depth survey of level line-array by analyzing symmetric relation of the real source position and the virtual source position. In this paper, the simulation results and experimental data are analyzed and compared, the accuracies of the depth scanning under different conditions are discussed, and the accurate localization results for the target source are given.

Key words: acoustics, focused beam formation, underwater image, energy maximum, source depth measurement, multi-path
