摘　　要：研究了电磁波遇到障碍物而产生绕射的规律。根据障碍物的拓扑结构的不同,分别对刃峰绕射、圆顶峰绕射、小坡度连续地面绕射进行分析研究,得出了相应的绕射公式,随后研究了多山峰实际地形绕射因子的计算,这对研究电磁波遇到障碍物时的绕射有较好的参考。This paper studies the rule of diffraction generated when the electromagnetic wave propagation falls across barriers.According to the difference of topological structures of barriers,this paper analyzes and studies the diffractions of single knife-edge,flat-topped obstacle,little grade ground,and fetches the corresponding diffraction formulas,then studies to calculate the diffraction faction of the practical physiognomy of multiple knife-edge mounting,which has good reference to the electromagnetic wave propagation diffraction over barriers.
