Design and experimental application of circular array of vector underwater acoustic sensor

Abstract

Vector hydrophone is a new type of underwater acoustic sensor, which is one of the hot spots in the field of underwater acoustic technology in the 21st century. In order to explore the feasibility of vector hydrophone circumferential array in engineering applications, a 16-yuan composite vector hydrophone circumferential array is designed and manufactured in this paper. The array diameter is 1.92m and the working frequency band is 20~3000Hz. The experimental results show that the array has better target azimuth estimation ability than scalar circular array.
