Abstract

Two designs of parametric sonar with respect to their linear counterparts which usually used as harbor and port security sonar are presented. One design is working at the frequency of 30 kHz according to the frequency of a linear sonar, but this frequency is the difference frequency for the parametric sonar whose primary frequency is 90 kHz. The other is working at 10 kHz with primary frequency of 60 kHz which is the working frequency of another linear sonar. Calculation and analyzing demonstrate that the nonlinear designs have better performance in reverberation limited environment while the linear ones work better in noise limited environment, when their apertures are the same size. This suggests that parametric sonar will have better performance at costal shallow water area where the boundary reverberation is usually the most important limiting factor for active sonar performance.
