The synthesis problem of the waveguide array according to the prescribed amplitude and power radiation pattern is considered. The mutual coupling of the separate elements of array is taken into account in the process of solution of a direct problem (analysts problem). Variational statement of the synthesis problem is used. The functionals representing a mean-square deviation of the prescribed and received radiation patterns are minimized. The corresponding nonlinear equations are reduced; and the modeling results are shown.References
