FIELD: radio engineering, communication.
SUBSTANCE: invention relates to radar and can be used in superheterodyne-type receivers. The interference self-compensator comprises a superheterodyne-type main receiving channel, a heterodyne of the main receiving channel, M compensation channels, a multi-input addition unit, wherein each compensation channel comprises a compensation antenna, a mixer, an intermediate frequency amplifier, a compensation signal generating unit, a quadratic conversion unit, an adder, an additional mixer, a phase changer, a subtraction unit, an additional intermediate frequency amplifier and an additional compensation signal generating unit. The listed devices are made and connected to each other in a certain manner.
EFFECT: high noise-immunity of an image receiving channel.
