摘要

提出了一种基于均匀几何衍射理论(UTD)的火箭形结构天线分析算法。对Yu和Burnside(1972)的高程平面理论进行了扩展，使得即使震源位于结构的其他部分也可以进行分析。该理论通过Ryan(1972)的结果得到验证，该结果基于对结处磁边电流的估计。用标准曲面衍射理论得到了滚转面和方位面的辐射方向图，与已发表的理论或实验结果吻合较好。

Principal plane analyses of a monopole antenna on a rocket shaped structure using UTD

An algorithm is developed based on uniform geometric theory of diffraction (UTD) for the analysis of an antenna mounted on a rocket shaped structure. Yu and Burnside (1972) elevation plane theory is extended, so that analysis can be done even if the source is located on other parts of the structure. The theory is validated with Ryan's (1972) result which is based on estimation of magnetic edge currents at junctions. The radiation patterns in the roll and azimuth planes are obtained using standard curved surface diffraction theory and agree well with published theoretical or experimental results.
