英文摘要：

An effective approach for calculating the far field pattern of conformal arrays mounted on curved-surface platform is proposed.Starting from the superposition principle for arrays,an active element pattern technique including element mutual coupling effects is used to illuminate the radiation characteristics of arrays.And then the proposed theory of an active element pattern technique combining with the element polarized pattern transformation is applied to analyze a curved-surface conformal array.By dividing all elements into different parts,a large array problem can be divided into a superposition of various simplified sub-array problems and greatly reduces the computation burden.Numerical results show that the proposed method is valid.
