| 摘 要： | 传统的SAR仿真及成像处理主要基于科学计算软件的大量数学运算,提出了一种机载SAR海洋场景的可视化仿真系统。本仿真系统基于C/S架构,客户端基于OpenGL渲染场景,主要包括动态海洋场景绘制、飞机三维模型导入、机载SAR扫描过程模拟、网络通信、SAR回波成像显示等模块,服务器端负责基于GPU并行计算海洋的SAR仿真回波。系统运行及仿真结果表明,本系统可以较为逼真地实现机载SAR海洋场景的可视化。

| Abstract: | Traditional SAR simulation and images processing are mainly based on the large complexity computation of mathematical software.This paper presents an airborne SAR of ocean scene visual simulation system.This simulation system is based on the Client/Server structure.The client renders front-end scene with OpenGL,including drawing dynamic ocean scene,loading 3D model of flight vehicle,airborne SAR scan simulation,network communication,SAR echo imaging and display,etc.The server is responsible for the computation of ocean echo,based on the GPU parallel computation.The simulation system and the simulation result show that the method can be used to implement the visualization of airborne SAR in ocean scene. |
