Abstract

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
