Abstract

The use of a parametric array as an acoustic source for measuring the acoustic properties of materials for use in sonar systems is considered. Techniques of measuring the wideband transmission and reflection properties of limited size test panels are described and the advantages of using a parametric array in terms of reducing edge diffraction errors are discussed. Results for a range of materials under ambient pressure over the range 10–200 kHz are presented to illustrate the potential of the technique. The implementation of the approach in a pressure vessel at the UK National Physical Laboratory is also described and illustrated with example results obtained over the frequency range 2–50 kHz for two test objects that have predictable behavior. The potential of the technique is also illustrated with experimental results for viscoelastic test panels for hydrostatic pressures up to 2.8 MPa
