FIELD: radio engineering, communication.
SUBSTANCE: method of calibrating receiving radio links of a radio interferometer and a device therefor include monitoring and adjusting the amplitude and phase identity of the receiving radio links of the radio interferometer in a wide frequency range and at different distances between receiving antennae.
EFFECT: high accuracy of forming a calibration database and cutting the required number of cable links by half.
