Abstract :
A new phase synthesis method for planar and conformal arrays is presented. The method is based on approximate linearized equations for small phase changes in the excitations, which can be determined by the least-squares method and used iteratively to obtain the final solutions for the excitation phases. Several different kinds of contoured beams can be used in the same array by using only phase shifters in the elements, as demonstrated in the calculated synthesis examples
