The results of an experimental program designed to measure the spectral characteristics of underwater bistatic surface scatter as a function of sea state and geometry are presented. The sea states examined were all small but because of the short acoustic wavelength the square of the Rayleigh parameter ranged from 4.45 to 108.1 with all but one of the measurements in the very rough regime. Both specular and off-specular data were collected. A plane wave theoretical model was used heuristically to indicate the trends to be expected in the data. It was found that, in general, the plane wave model did not adequately predict the results although in certain special circumstances its results were accurate. Areas requiring additional effort are discussed. Author
