Analysis of Basin Backscattering in the Levantine Sea
Abstract
Research has been conducted in the Levantine Sea basin to measure low-frequency basin reverberation and relate the measurements to backscattering strength. The receivers were a towed horizontal array and a suspended vertical array. SUS (0.818 kg) charges were used as sources. In this broadband basin, reverberation data were collected simultaneously from the towed and vertical array. The towed-array data were taken on multiple headings; combining different headings permitted removal of the ambiguous directionality information from the towed array. Frequency domain beamformed data are presented for 100, 300, 450 and 715 Hz. Estimates of backscattering strengths of different features are provided and are in the range quoted in other publications. Statistics for the dominant backscatterers are given, relating scattering strength to incident angles on slopes.
