Abstract
As part of a development project sponsored by DRDM and DMCS on Spectra Fiber composite sonar domes, DREA has been tasked to provide data on the acoustic properties of glass and Spectra Fiber based composite panels in a 2 - 10 kHz range. The low frequency and high level of accuracy desired presented a number of challenges for carrying out insertion loss measurements. This paper introduces the use of parametric arrays to generate broad frequency responses off sonar dome materials. Particular attention is placed on the generation of low kHz signals in a laboratory limited tank setting and the resultant measurements produced.
