Numerical study on SAR-based rogue wave detection part one: SAR image simulation

The scarcity of ground-truth data for intercomparison and validation obviously limits the development of rogue wave detection algorithms from synthetic aperture radar (SAR) images. In this study, a numerical method of SAR image simulation for the purpose of validating rogue wave detection algorithms is proposed. Our work is divided into two parts, this first part focuses on SAR image simulation unique in that enhanced high order spectral (HOS) model and two-scale rogue wave sea surface model are included, by which we take nonlinear interaction of rogue waves and Bragg short waves into account and get vivid three-dimensional (3D) rogue wave sea surface and SAR images. Our work contributes to the experimental operational use of SAR data for the remote sensing of rouge waves.
