Computer Aided Parametric Sonar Design Update.

Abstract

A computer program was written that simplifies the design of parametric sonars. This program has since been modified to update the calculation for secondary directivity index and to include calculations for secondary beamwidth and primary beamwidth. The tolerance on the determination of secondary source level has been reduced from + or - 1.0 dB to + or - 0.5 dB with a consequent tightening of tolerances on all other related calculated quantities. Finally, a new plotting method has been introduced to give plots in the form of families of curves for ease of design analysis. (Author)
