The algorithms for measuring angular coordinates оf pair aims which is not resolved by distance or speed or by angle by the Rayleigh criterion was proposed earlier. The advantage of given algorithms is that it needs only two receiving channels to divide signals from aims. The shortcoming is incomplete usage of transmitting antenna. The article proposes an algorithm of forming space-time signal emitted at two at two frequencies and algorithm for measuring angular coordinates оf pair aims using such signal. The result of mathematical modeling which are proves advantages of proposed algorithm for measuring angular coordinates is given.
