Abstract
Aperture integration-surface integration algorithm is studied,which is used to analyze the electromagnetic radiation properties of radome-enclosed antenna.In the course of surface integration,uniform phase is replaced by linear phase with introducing Gordon formula,as the linear phase is more close to the real situation of radome surface.The validity of the improved algorithm is confirmed by a simple numerical example,and the simulation results show the efficiency and precision of radiation pattern of radome-enclosed antenna are raised greatly by using improved algorithm.
