Abstract :
A simple empirical formula is presented for computing the reflection coefficient of a rough-sea surface using windspeed, angle of incidence, and frequency as parameters. The formula closely mimics the Beckmann-Spizzichino loss model, from which is was derived. Error contours are presented, which illustrate the closeness of fit between the two approaches.<>
