Abstract

In this paper a vertical array for localizing the range and depth of the sound source in shallow water is presented. The array consists of three segments,and its total length is 120 m.The work-segment consisting of 25 fluxed circular plates is 40 m in length. The sensitivity of the elements is -192± 1.5 dB (re 1 V/μPa) in the frequency range from to Hz to 2.5 kHz, and the phase difference is less than 5°.The acceleration sensitivity is -60dB (re 1 V/g). An experiment was carried out in the Yellow Sea in August of 1992. The result is quite satisfactory.
