| 摘 要： | 针对雷达探测范围会受到复杂地形因素影响,单一地依靠电磁传播模型可视化雷达探测区域很难真实有效地展现电磁覆盖情况的问题,该文提出一种基于GeoSOT-3D空间剖分的雷达探测范围的计算与表达一体化的真三维模型。GeoSOT-3D剖分框架将上至地球50 000km,下至地心的全部地球空间划分成多层次、多尺度空间体元,体元可承载多源异构空间数据。依据GeoSOT-3D的剖分流程,将地形数据、雷达探测空间数据离散化。最后,开发了雷达探测范围可视化验证平台。实验结果表明,该建模方法对复杂的地形适应性强,可视化表现效果真实直观。

| Abstract: | According to the fact that the range of radar detection is generally affected by complex terrain,it's difficult to visualize the electromagnetic coverage only rely on the electromagnetic propagation model.A global multi-scale 3D spatial data representation model based on the GeoSOT-3D frame was presented in this paper.The global discrete voxel divided the earth into a series of different scale voxels.The GeoSOT-3D framework was an illimitably divisible,multi-level,multi-scale space division pattern,which can seamlessly fit the global space.The model tried to represent the terrain data and radar detection spatial data,and then a new three-dimensional model of radar detection range was proposed.At last,in order to verify the theory presented in this issue,we constructed a platform for radar detection range visualization prototype system using the representation method.The experimental results showed that the modeling method had a strong adaptability to complex terrain,and the visual display was real and intuitive. |
