Abstract. The method of permission of signals in active radar systems is offered. Stability of the decision is provided as at the expense of finite-dimensional approximation of the operator of transformation of system, and supervision model. It is supposed that supervision model an essence finite-dimensional set of projections in a subspace of the orthogonal (unitary) matrixes which have been functionally connected with a matrix of the initial linear operator of transformation of system. The results of the imitating mathematical modeling confirming high efficiency of the offered method of permission of signals are presented.

Keywords – permission, resolution, condition number, matrix of the linear operator, singular value decomposition.
