A physical radar simulation tool of the sea clutter

Abstract

This paper describes a fast simulation tool for computing a sea surface remotely sensed by radar, by using parallel computing on GPU cards. The electromagnetic backscattering model is based on the two-scale model, with the incorporation of shadowing and spike effects at low-grazing elevation angles. The contribution of breaking waves is analysed. This intuitive and interactive simulation tool offers the possibility to test a large range of environmental and radar configurations through the various functionalities of its graphical user interface.
