High-Frequency Bistatic Reverberation from a Smooth Ocean Bottom

Abstract

High-frequency bistatic reverberation was measured from a smooth, sandy, featureless bottom located 19 miles south of Panama City, FL. Bistatic scattering variability is presented as a function of frequency (20-180 kHz), grazing angles (9.50 deg -30 deg), and small horizontal and vertical bistatic scattering angles. Results show that bistatic variabilities tend to decrease with decreasing grazing angles and decreasing source beamwidths. Possible explanations for these decreasing variations are also presented....
