The research in the paper puts forward a novel method for synthesizing conformal arrays and optimizing low cross-polarizations including the effects of element mutual coupling and mounted platform. Starting from the far-field superposition principle, an efficient approach with active element pattern technique is proposed to calculate the far-field patterns. Coordinate transform is used to create polarization quantities, and a general process for the element polarized pattern transformation is proposed. The two numerical examples are proposed, and the desired sidelobe levels and low cross-polarizations are optimized. Numerical results denote the proposed method is valid.
