针对野外地形的电磁环境仿真，提出一种基于野外优势路径电波传播模型的可视化方案，利用野外优势路径模型构建仿真核心，并与Okumura-Hata模型和峰脊衍射模型（ knife edge diffraction model ）进行仿真对比，证明野外优势路径模型能得到更接近事实的结果。使用ASTER GDEM V002数据构建带有真实高程信息的三维野外地形模型，使用Qt基于项的图形视图技术绘制二维视图，使用OpenGL绘制三角面片的方法构建三维视图。并以黑龙江五常市南部地区为例进行电磁仿真预测，验证方案的可行性。

This paper proposed a visual solution based on rural dominant path model for field electromagnetic envi -ronment simulation .The simulation core was built using the rural dominant path model and compared with Okumura-Hata model and knife edge diffraction model , showing that the rural dominant path model can get the result closer to the truth.The three-dimensional wild terrain model was constructed by ASTER GDEM V 002 data which have re-al wild terrain elevation information .Two-dimensional view was drawn through Qt graphical view technology and three-dimensional view was drawn by triangular rendering method of OpenGL .Finally taking the southern area of Wuchang City , Heilongjiang as an example for electromagnetic simulation , the feasibility of the scheme is verified .
