| 摘 要： | 针对雷达波与孔缝腔体内复杂传输线耦合计算问题，提出一种基于矩量法、并矢格林函数和传输线Π等效电路与Agrawal混合模型的计算方法．首先，用矩量法求得雷达天线在孔缝处的入射电磁场; 然后，采用矩量法-并矢格林函数混合算法计算孔缝处等效磁流，并求得腔体内的电磁场; 接着，运用所得电磁场与传输线混合模型计算传输线的负载电流响应．通过仿真传输线与BLT方程等计算结果比较，验证了此方法是有效的．

| Abstract: | Aimed at coupling calculation for radar waves and aperture cavity complex TL, a calculation method is proposed based on the MoM, the dyadic Green's function (GF) and mixing of the Π model and Agrawal model. First, the incident electromagnetic field at the aperture of the radar antenna can be obtained by the MoM. Then the MoM-GF hybrid algorithm is used to obtain the equivalent magnetic current in the aperture and the electromagnetic field inside the cavity. Finally, the TL load current response can be calculated with the result of electromagnetic fields and the hybrid TL model of the equivalent Π circuit and Agrawal. Throuth TL simulation results by the BLT equation this method can be validated effectively. |
