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。
In this paper, the high-order moments method is used to calculate the radiation pattern of a UHF radar antenna installed on a transport aircraft. The calculated results are analyzed and compared with the common RWG method, multi-layer fast multilevel sub-algorithm The required computing resources are compared. Computing computing platform used for ordinary desktop workstations. Due to the limitation of computing resources, commercial software based on RWM method can not accomplish this task on the same benchtop workstation. Multi-layer fast multilevel sub-class is prone to iterative non-convergence.
