Abstract: Tolerance synthesis techniques of array radiation pattern are investigated. The mathematical models for array radiation pattern optimization are given, and the methods for solving the problem of tolerance optimization are initiated. The physical model for arbitrary tolerance distribution of array elements is presented. Numerical examples are given for the broadside array in which the excitation amplitude coefficients have tolerances. The methods given in this paper immunize optimally the resulting arrays against the deviations of the design parameters from their nominal values. -
