FIELD: antenna engineering. SUBSTANCE: suppressor has main and auxiliary antennas with circuits of series-connected low-noise amplifier, mixer connected to heterodyne, and intermediate-frequency amplifier connected to each of them, limiter connected to output of intermediate-frequency amplifier in auxiliary antenna circuit, as well as common-mode and quadrature circuits for shaping control signals to control power of adjustable attenuators inserted in noise amplitude and phase control circuits which ensures its coherent compensation in subtracting device. Each of mentioned shaping circuits has series-connected low- frequency amplifier and limiter both connected past multiplier. Limiter functions to restrict output signal fluctuations in low- frequency amplifiers at high-intensity noise. EFFECT: improved operating stability and coefficient of noise suppression at high-intensity noise. 5 dwg
