High Frequency Bottom Back Scattering in the Darwin Area.

Abstract

The backscatter of acoustic energy from the sea floor has been measured at acoustic frequencies of 34 kHz, 100 kHz and 205 kHz. Measurements made at several sites near Darwin are reported. Measurements were made as a function of grazing angle and azimuth. During the experiments site environmental measurements were made to characterise in detail the area of the acoustic measurements. The locations, equipment and techniques used during the measurements are described.
