GPU-Accelerated Computation of EM Scattering of a Time-Evolving Oceanic Surface Model II: EM Scattering of Actual Oceanic Surface

Based on marine environmental factors of different sea areas, a high-performance clutter time series modeling algorithm for the real surface is developed to study amplitude mean and Doppler spectrum characteristics clutter. The European Centre Medium-Range Weather Forecasts (ECMWF) data set (ERA-Interim) ESA’s soil moisture ocean salinity (SMOS) are utilized establish databases factors. Combined with mixed model, geometric fine structure wind-driven swell superposition established by using double-superposition method (DSM) comprehensively considering small-scale capillary ripples, large-scale gravity waves swell. A triangle facet-based developed, in which quasi-specular scattering based wave modulation calculated, respectively, compared measured results. For high-resolution radar, dynamic calculation very consuming. In this paper, Tesla K80 GPU manufactured NVIDIA Santa Clara, Computed Unified Device architecture (CUDA) parallel technology some optimization strategies adopted improve efficiency modeling. results can be used analyze distribution factors, average areas.
