FIELD: instrumentation engineering; noise suppression devices. SUBSTANCE: device that functions to generate directivity pattern zero in antenna arrays wherein part of antennas failed in the course of service to compensate for mutual impact of antennas, impact of structural components, and array manufacturing defects by using information about useful signal amplitude and in some cases to compensate for pattern-generating circuit error has antennas, pattern-generating circuit, and weighting coefficient computer. Signals picked off antenna output are conveyed to pattern-generating circuit; the latter conducts weighted addition of signals arriving from antenna outputs, weighted coefficient computer finds weighted coefficients of pattern-generating circuit; amplitudes and phases of signals arriving from outputs of antennas are entered in weighted coefficient computer; as distinct from prior art, amplitudes and phases of signal across pattern-generating circuit and amplitudes of useful signal are entered in addition in weighted-coefficient computer. EFFECT: enlarged functional capabilities. 7 cl, 2 dwg
