Wind dependence of L-band radar backscatter
Abstract
Like other microwave frequency bands, L-band scattering coefficient measurements have shown a definite dependence on ocean surface wind speed (W). The relationship between the two depends on the observation angle of the radar. The satellite-borne L-band radars Seasat-SAR and SIR-A made observations at fixed incidence angles, while the just completed SIR-B mission has made observations at multiple incidence angles. The present work uses the theory of scattering from a composite surface and generates an analytic function of the relationship between the scattering coefficient and W for varying incidence angle at L-band by the method of empirical curve fitting.
