| 摘 要： | 利用机载SAR进行对地观察的飞行实验所需时间和处理周期偏长,成本也偏高,并且没有定量的地形遮挡分析。文章利用三维数字地球平台的地理信息,提出一种基于Xdraw算法的机载雷达可视域分析。只要给出地形的数字高程模型（DEM）数据,就可以得出可视域的分析结果,同时在不同SAR航线高度参数下对算法进行了验证和分析评价,得出该算法可以较好近似真实的可视信息,为SAR实验给出了定量的地形遮挡分析,为确定SAR航线规划提供了可靠的参考。

| Abstract: | Airborne SAR experiment on terrain observation suffers from long processing time,high costs as well as lack of viewshed analysis.In this paper,an Xdraw algorithm based SAR viewshed analysis exploiting geographic information system(GIS) provided by 3D-digital Earth Platform is proposed.Given the terrain data of digital elevation model(DEM),the result of viewshed analysis can be acquired.Numerical results for different SAR flight height are obtained for verification and evaluation.The result shows that this a... |
