Paper Abstract

The wave number spectrum of a well developed sea includes a broad range of wavenumbers (the equilibrium range) where the spectral density is governed by a power law k P. In the approximation of a Causaussian surface, the exponent p is related to the Hausdorff dimension by DH =(8-p)/2 For p < 4, Dh exceeds 2, and the surface is character-ized by an increased number of steep and breaking wavelets and by an increased number of specular points at near vertical incidence. The former results in the so-called spike component in the total return at oblique incidence, whereas the latter leads to an increased backscatter at nadir and near-nadir angles. Theory for both cases is reviewed and implications for satellite scatterorneter and altimeter measurements of surface winds are discussed.
