FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering, namely to microwave receivers, and can be used in radar systems with several channels for receiving reflected signals. Three-channel microwave receiver with double frequency conversion comprises a first bandpass filter at the input of the first channel, a second bandpass filter at the input of the second channel, a third bandpass filter at the input of the third channel, a first conversion unit, a second conversion unit, a DC-DC converter and an output signal unit, and additionally comprises, in the first conversion unit, two notch filters and three frequency multipliers, and in the second conversion unit – three attenuators.
EFFECT: high accuracy of measuring angular coordinates of a target when used in monopulse radar stations.
