Maximization of signal-to-noise and interference relation (SNIR) or an energy optimization is one of the trends in the optimization of array integral parameters.

In spite of the defining role of the SNIR in providing an accuracy of the monopulse radar systems there are no published papers on the energy optimization for the monopulse arrays.

The purpose of the present paper is the development of the energy optimization method for the total-difference, beam-shared-forming monopulse arrays, that is for such arrays, in the channel of each radiator of which there is one device of a complex weighing J_n (n = 1, 2, …, N). In such arrays forming of two beams of the monopulse group is provided by the way of using two adders, the inputs of which are connected with the devices of complex weighing through the fixed shift-phasers, providing a progressive increasing (for the first beam) or decreasing (for the second beam) phase shift.
