| 摘 要： | 采用矩量法(MOM)结合一致性绕射理论(UTD)来计算共形天线阵单元间的互耦。这种混合方法通过UTD来修正MOM中的广义阻抗矩阵将理想导体曲面对天线的影响考虑在内。克服了单独采用这两种方法的缺点。既减少了计算量又达到了一定的精度。计算结果与文献中已有的结果吻合得相当好。

| Abstract: | The problem of calculating the mutual coupling between two elements of conformal array is considered. The mutual coupling is calculated by a combination of method of moments (MOM) with uniform theory of diffraction (UTD) .The hybrid method modifies the usual impedance matrix in MOM to account for the effects of the conducting body via UTD. This reduces the memory requirement as well as computer processing time and provides an efficient and costeffective solution in some problems. The results are verified against results found in literature. Good agreement is obtained. |
