Abstract:
The method of decision for the twocriterion problem of array synthesis is offered on the basis of fuzzy sets apparatus, taking into account requirement to the size of antenna array radiation pattern rejection from the need pattern and variation of currents norm in the antenna surface. Procedure of the array synthesis problem decision with the using of Lagrange-s multipliers method is complemented procedure of searching for optimum Lagrange-s multiplier on the basis of fuzzy sets apparatus. Thus the area of allowing solutions is generated by the change of the Lagrange-s multiplier value. On the sets of mean square rejection and norm of currents values determines the fuzzy sets are entered by the task of belonging functions. Crossing after the Zadeh of fuzzy sets working out the optimum parameter of the synthesis problem.
