基于MapX的短波通信覆盖能力显示方法

Method of Showing HF Communication Field Based on MapX

为了在地图上直观地实时显示出短波通信的覆盖能力,论文利用GIS控件MapX对地理对象的显示和分析功能,在VC中调用短波计算软件计算并得到覆盖分布数据,将得到的数据利用改进的Delaunay三角形剖分算法生成三角形网格,并利用等值线追踪算法绘成等值线,在等值线之间填充相应颜色,最终在MapX中显示出通信覆盖范围。

In order to show HF communication field on the map intuitively, the function of display and analysis to geographic object by MapX is used. Short wave calculation software is used to calculate and get the field strength distribution data in VC programming. The data was generated triangular mesh by used improved Delaunay triangle subdivision algorithm, and then drawn contour by used contour tracing algorithrm Finally, the corresponding color is filled between the contour lines, and the HF communication field coverage is showed on MapX.
