摘要

本文介绍了一种基于GPU卡并行计算的雷达遥感海面快速仿真工具。电磁后向散射模型基于双尺度模型,考虑了低掠射仰角下的阴影效应和尖峰效应。分析了破碎波的作用。这种直观的交互式仿真工具通过其图形用户界面的各种功能,提供了测试大范围环境和雷达配置的可能性。

A physical radar simulation tool of the sea clutter
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.
