ANALYSIS OF MUTUAL COUPLING OF CONFORMAL ARRAYS ON ARBITRARY SURFACES WITH REVOLUTIONAL SYMMETRY

摘要: 本文研究了旋转对称面共形阵互耦的分析方法。文中提出了等效环的概念,把旋转对称面上不等元分布共形阵等效为等元分布的情形,简化了共形阵的物理模型。通过把阵的任意激励分解成与结构对称性相匹配的一组本征激励的线性叠加的方法,避免了大矩阵的求逆,大大的减少了运算量。这对于共形阵的分析和综合有重要意义。

Abstract: This article presents the mutual coupling of conformal array on arbitrary surfaces with revolutional symmetry. The concept equivalent ring simplifies the array model in the method of equating arrays with unequal elements to arrays with the same elements in each ring. The method of decomposing the arbitrary excitation of arrays into a term of intrinsic excitations aviods the inversion of large matrixes and so reduces largely the computer tune, which is very important to the analysis and synthesis of conformal arrays. -
