-
摘要: 本文研究了三维复射线理论,给出了三维空间中一般的复射线追踪法,对旋转抛物形单层介质天线罩的波束传输特性进行了计算.根据计算出的数据绘制了远区和近区波束传输特性方向图,并与无介质天线罩时波束方向图进行了对比,从而明确了天线罩对波束传输的影响.Abstract: The complex ray theory for three-dimensional space is researched, from which the method of complex ray tracing for arbitrary configuration in three-dimensional space is derived, and the beam transmission properties of a rotating parabolic radotne are solved. According to the data calculated. the patterns of the beam transmitted through a rotating parabolic radome are plotted. Then they are compared with the patterns without radome and the effects of radome on the beam transmission is depicted.
