复杂场景微波辐射图像的模拟

Simulation of microwave radiometric images on complex scene

模拟生成微波辐射图像是为了用其作地形匹配制导中的基准图。文中分析了光学图像和微波辐射图像之间的几何关系,讨论了光学图像的分割、识别及表面方向获取的方法,论述了地物表面温度、亮度温度、视在温度、天线温度和天空温度之间的关系,并在此基础上提出了一种模拟生成复杂场景微波辐射图像的方法。仿真结果表明,方法完全可行。

After the geometric relation between optical image and microwave radiometric image is analyzed, the optical image segmentation and classification are described and the method of giving shape from shading is given. Then the computation of the brightness temperature of the terrain and sky is presented, and the method of computing the antenna temperature of the terrain is given. A new technique is introduced to generate the microwave radiometric images on complex scene from the optical images. The technique is expected to be a useful tool to generate the source images of the matching navigation. For comparison, two passive microwave radiometric images are presented, which one is profiled by the 8 mm ground\|based microwave radiometer and the other is generated by this technique. \;
