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. -
