摘　　要：为了在资源有限的条件下快速准确地分析电大尺寸天线罩的透波特性,给出了1种等效源结合区域分解的计算方法。天线部分预先计算出近场等效源为后续计算节约内存消耗和计算时间,天线罩部分用区域分解法分块计算,所有计算资源集中计算单个子区域,进一步降低了内存需求。数值仿真实例表明,该方法可以准确高效地解决X频段带罩天线辐射问题。In order to analyze the transmission characteristics of electrically large radome rapidly and accurately under the condition of limited resources,a method of equivalent source combined with domain decomposition method is presented.The near-field equivalent source is calculated in advance in antenna part to save the memory consumption and calculation time for the subsequent calculation and the radome part is calculated by the domain decomposition method,this further reduces memory requirements.The numerical simulation shows that the method can solve the radiation problem of X-band radome antenna accurately and efficiently.
