    摘要： The invention relates to radar and can be used in radar posts using the phase method of measuring the angular co-ordinates of moving objects for guidance systems which use calculations of target positional data. The proposed system comprises the following elements: a multichannel receiving antenna-feed system and frequency converter; back-up and measurement channel receivers; a calibration signal circuit; a signal processor; a Doppler frequency synthesiser (connected in series to the output of the back-up channel receiver); a multichannel Doppler frequency filter, detector and meter (connected in series to the output of the multichannel Doppler frequency filter); a multiplexer, a heterodyne frequency converter whose second input is connected to the heterodyne output, a power divider, a second mixer whose signal input is connected to the first output of the frequency converter, a band-pass filter, an amplifier, and a phase meter. The second output from the power divider is connected to the heterodyne input of the first mixer of the measurement channel receiver whose output is connected to the second input of the phase meter; the output of the Doppler frequency synthesiser is connected via a switch to the control input of the controlled attenuating circuit whose signal input is connected to the passive divider, while its output is connected via the calibration signal circuit to the communications unit of the receiving antenna-feed device and calibration signal circuit.
