FIELD: radio engineering, communication.
SUBSTANCE: invention relates to radar and is intended for use in monopulse radar stations. The radio direction-finder comprises two receiving channels, each consisting of a mixer, an optimum filter, a linear intermediate frequency amplifier and a detector, as well as a heterodyne, a first addition unit, a first subtraction unit, a first division unit, and additionally five division units, six multiplication units, two addition units, two subtraction units and a reference voltage source. The listed devices are made and connected to each other in a certain manner.
EFFECT: high accuracy of measuring angular coordinates.
