| 520 | 3 |a"Two theoretical investigations are given relating to SAR imaging of perturbed surface waves. The first is an analysis of the effect of a long wavelength corrugation on the SAR image formed by 1st-order Bragg scattering from a deterministic sea wave pattern such as a Kelvin wake. A standard SAR processor is assumed. The second is a stochastic treatment of the SAR imagery formed by a 1st-order Bragg scattering process from surface waves modulated by the horizontal surface currents of internal waves. Propagational velocities (normalized by the SAR platform velocity) are included to first order. For the Kelvin wake analysis it is shown that the vertical curvature of the corrugating wave can rotate the effective Bragg acceptance angle by up to approximately equals to 10 degrees for typical wave parameters.
