Abstract: In this paper , a method of the Aperture-Integration, Surface-Integration and Adaptive Grid (AI-SI-AG)for ultra-wideband airborne radome analysis is presented. The theoretical results byAI-SI-AG and measured data are given. It is found that by this method the pattern of omni-directional-antenna and directional-antenna enclosed in radome can be computed efficiciently and the theoretical results agree with measurement quite well. It has shown significant practical value in engineering applications. -
