Abstract
Direct numerical simulations of the ocean-to-SAR mapping and the corresponding spectral transform have been carried out using both the linear Gaussian wave model and random Gerstner waves. It is demonstrated that specular reflection can play a significant part in the RAR imaging process for steep range travelling waves. Some consequences for the SAR image spectra are illustrated for both wave models.
