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 transducerhydrophone 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.
