Preliminary Analysis of Echo 2000 Data

Abstract

In this report some preliminary results from target scattering measurements made at the DREA barge in April 2000 are presented. Various targets were mounted on a pole at about 5m distance from a transducer/hydrophone arrangement. The transducer allowed for the generation of harmonic bursts in the 10-100 kHz range and the scattered signals received at the hydrophone were recorded. This data was collected for a plate, spheres, cylinders, and a rock for a variety of centre frequencies and azimuthal orientations of the targets. A very large amount of data was collected and it is not possible to give a comprehensive presentation of the data; instead an interesting sampling of some of the results of our analysis of the data are presented.
