FIELD: physics, navigation.
SUBSTANCE: invention relates to the field of radar equipment and can be used in the radar monitoring systems with the phased antenna arrays. It consists of receiving-transmitting phased antenna arrays with the phase shifter control unit, summator of receiving channels of the phased antenna array, connected with a comparison circuit and the signal selection unit. Also the additional modulator of the reference channel of the phased antenna array is added, connected through the additional selection unit with a comparison circuit and the phase shifter unit.
EFFECT: technical result consists in improvement of precision of monitoring of channels at fluctuations of the level of reflected signals.
