Sea Surface Reflection Strength from Acoustic, Radar, Laser, and Slope Spectra Measurements

Measurements for various wind speeds v of wind-blown water surface characteristics by acoustic, radar, and two optical means provide estimates of sea surface reflection strength. The analysis suggests that reflection strength decreases about as vexp -1 from near unity for wind speed less than five knots to an asymptotic value of approximately 0.1 above 20 knots with an uncertainty of a factor of 3. As an aside, correlation lengths for sea surface slope and curvature are estimated by manipulation and integration of the slope spectra measurements.
