摘要
Abstract
Underwater multicell single-layer thin metal plate corner reflectors can't form a relatively stable TS in a large space because of its strong frequency characteristics.To solve the problem,the paper designs the underwater multicell cavity corner reflectors.Then using FEM coupled DBEM solver to simulated its scattering acoustic field in incident wave frequence varies from 5.0 kHz to 15.0 kHz.The results show that the underwater multicell cavity corner reflectors has weak frequency characteristics,obvious decoupling effect and strong scattering ability.Underwater multicell cavity corner reflectors can main-tain stable target strength in a large space,and has better reflection ability,so it is an ideal underwater acoustic reflection device.关键词
