摘要
采用矩量法面积分方程(SIE)分析波导缝隙天线阵问题时,由于矩量法中缺少理想吸收边界的概念,所以难以模拟匹配负载,行波天线的计算比较困难。同时大型天线的仿真计算非常耗时。针对这些问题,本文通过基于孔径耦合的等效原理和波导的模式匹配法构造出矩量法中的波端口模型。通过波端口模拟的匹配负载实现了行波天线的准确计算。另一方面通过引入并行计算技术,以超级计算机为平台实现了大型波导缝隙天线阵的快速仿真计算。与商业软件计算结果的对比验证了该方法的正确性和高效性。
When calculating the radiation problem of slotted waveguide antennas based on Mo M, the lack of absorbing boundary makes it difficult to simulate the matched terminator. Therefore, It is difficult to calculate the travelling wave antennas. At the same time, the simulations of electrically large antennas need too much computation. To deal with these problems, the model of wave port which is based on cavity equivalent principle and mode matching is presented. The matched terminator constructed in this paper helps simulate the travelling wave antenna accurately. In other hand, the introduction of parallel technique can improve the ability of Mo M to deal with electrically large target. With the help of super computer, this paper realized the quickly simulation of electrically large slotted waveguide antenna array. The result of this paper has been proved correctly by the comparison with commercial software.
