一种基于连通原理的射频发射覆盖范围近似表示

An approximate representation based on connection theory of the coverage area of RF transmission

在传统的数据电台组网通信系统的基础上,为了清晰直观地向电台用户展示发射电台覆盖范围,提出了一种近似的表示方法。通过获知发射电台定位信息、最大传输距离及接收电台高度,并经过相关的数学运算,最终在地图上标示出该条件下射频发射的覆盖范围。在不考虑衍射、反射和透射的情况下,该表示方法具有较好的近似性,已成功地用于数据电台通信连通性判断,并在飞机航路规划及通信站点建立位置选择等方面显示出强大的应用前景。

Based on traditional data radio networking communication system,an approximate representing method is presented in this paper to clearly show to the radio user the coverage area of transmitter radio.By acquiring position information of transmitter radio,max transmission distance and height of receiver radio,the coverage area of RF transmission on the map is indicated by arithmetical calculations.This method has a preferable proximity regardless of diffraction,reflection and transmission,and can successfully estimate data radio communication connectivity.Moreover,it has a significant applicable potential in the planning of flight route and the selection of the location of communication station.
