Low-Frequency Surface Backscattering Strengths Measured in the Critical Sea Test Experiments

Abstract

Surface scattering strength (SSS) is one of key acoustic inputs to reverberation and active sonar models. This report presents significantly-updated results from 55 broadband SUS SSS measurements in 6 Critical Sea Test (CST) experiments. Since the time of the previously-published results of Ogden and Erskine (and Nicholas et al.), there has been a : 1) major reprocessing effort that extended the grazing-angle coverage of many data sets; 2) recalibration that particularly impacts the lowest frequency band results; 3) significant revision of all the CST wind-speed values; and 4) systematic removal of fish-scattering contributions. This reports documents the updated results, and archives the bistatic SSS data.
