FIELD: antenna equipment, control over complex weighing facilities in channels of monopulse antenna array in order to form zeros in sum and difference radiation pattern. SUBSTANCE: process of joint formation of zeros in sum and difference radiation patterns of monopulse phase array is based on weighing of signals received by each radiator, on their division into two channels, on summation of signals received from like outputs of dividers in correspondence with growing and decreasing phase shift ensuring deviation of each ray through ±DU by generalized coordinate where ΔU is distance of ray maxima to equisignal direction and on subsequent formation of sum and difference radiation patterns. For suppression of interference P weight coefficients of signals received by adaptive subarrays ( each including 2P elements ) located on edges of array are chosen from condition of equality to zero of initial radiation pattern in 2P directions away from directions of interference by ±ΔU and in 2P directions symmetric to them by generalized coordinate relative to equisignal direction. Weight coefficients in other elements taking into account phases of elements are chosen equal to their values, corresponding to specified or initial distribution. EFFECT: capability to form zeros in sum and difference radiation patterns by way of correction of amplitudes and current phases in part of radiators. 3 dwg
