摘要
讨论了一种复杂环境下线天线隔离度分析方法,此方法可以广泛运用于飞机、战车、导弹、舰船等复杂环境。采用一种矩量法(MOM)和一致几何绕射理论(UTD)的混合法,并结合二端口网络下天线间隔离度的知识来计算复杂环境下线天线隔离度。此混合法克服了单纯的矩量法难以计算电大尺寸系统中的天线,以及一致几何绕射理论的计算精度不够的缺点,最终能实现计算速度和计算精度的统一。
A method of analyzing isolation between monopoles in complicated environment with aircraft, chariot, missile, and etc. is researched here. The hybrid MOM-UTD method combined with a method of deducing isolation from two port network is adopted to calculate the isolation between the monopoles in complicated environment. The hybrid method overcomes the shortages using MOM or UTD respectively, and realizes the unity of computing speed and accuracy.
