高阶矩量法计算机身对雷达天线方向图影响

本文采用高阶矩量法计算了某型运输机上加装UHF 雷达天线的受扰后辐射方向图，对计算结果进行了分析，并与普通的RWG 矩量法、多层快速多级子等算法所需计算资源进行了对比。计算所采用的计算平台为普通的台式工作站。由于计算资源的限制，采用RWG 矩量法的商业软件无法在相同台式工作站上完成这一计算任务，多层快速多级子则容易出现迭代不收敛的情况。

Computation of Radiation Pattern of Onboard Radar Antenna Array using MoM with Higher-order Basis Function

This paper computes the radiation pattern of a UHF radar antenna array on a certain type of aerotransport usinghigher-order moment method and analyzes the result of the radiation pattern of onboard radar antenna array. The result ofhigher-order moment method was comparing with the results of RWG-MOM and MLFMM. The computational platform weused is only a personal workstation. The commercial software that using the MoM with RWG basis functions is not able toachieve this task on the same personal workstation due to the restriction of the computing resource, and the MLFMM oftenappears the fault of divergence in iteration.
