Abstract : In this experiment we placed a small plastic container with a mixture of rubber epoxy and steelball bearings on a sheet of fibreglass. The fibreglass sheet was then suspended in the DRDC Atlantic acoustic calibration tank. The sheet was then scanned by a conical beam from the wideband high frequency multi-mode pipe projector (MMPP) and the echo recorded. The goal of the experiment was to determine how easily the attached mine region could be distinguished from the echo of the fibreglass sheet. In addition, we modified the basic mine by placing a thin aluminum plate on top of it, a small tungsten carbide sphere on top of this and finally a thick aluminum disc on top of the basic mine shape. These different echos will be used in a computer-classification study.
