| 摘 要： | 介绍了近几年国外参量阵技术在浅海探测声纳、吊放声纳、鱼雷自导声纳、浅海水声通讯等方面的应用进展情况。针对频率为30kHz的线性小目标探测声纳,对原频90kHz、差频30kHz的非线性参量阵进行了性能估算,结果表明,参量阵声纳在高混响背景下探测小目标的性能优于线性声纳。文章还分析了参量阵声纳的新应用所面临的一些技术难点,给出了一种相对简单的宽带参量阵的实现方法。

| Abstract: | Recent applications of parametric array technology in shallow water detection sonar,dipping sonar,torpedo homing sonar and shallow water communication sonar is introduced briefly in this paper.A parametric sonar design according to the linear sonar whose working frequency is 30k Hz is analyzed.The primary frequency of the parametric sonar is 90 kHz and the difference frequency is the same as the working frequency of the linear sonar.It is shown that the parametric sonar has better performance than the linea... |
