介绍了近几年国外参最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,参最阵声纳在高混响背景下探小目标的性能优于线性声纳.文章还分析了参量阵卢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.

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 fequency of the parametric sonar is 90kHz and the difference frequency is the same as th eworking frequency of the linear sonar.It is shown that the parametric sonar has better performance than the linear sonar in reverberation limited environment.The encountered difficulties for parametric sonar in recent applicafions are also analyzed,and a relatively simple method to achieve broadband parametric array is suggested.
