Abstract: The paper describes the equations of the central vertical sectionand the transversal-strips of doubly curved reflector.It gives calculating for-mulas for far field radiation of the shaped-beam doubly curved reflector.The paper synthesizes and analyses the doubly-curved reflector by means ofcomputer.Established design-software can complete design of the shaped beamfor the doubly-curved reflector antenna,and gives all coordinate data of thereflector.
