FIELD: radio engineering, communication.
SUBSTANCE: invention relates to means of monitoring parameters of radar devices and calibration. The radar reflector comprises a modulating signal source, series-connected modulator and reflector, as well as series-connected coupler, receiver, pulse former, control unit and switch, the second input and output of which are respectively connected to the output of the modulating signal source and the first input of the modulator, the second input of which is connected to the second output of the coupler, the input of which is connected to the output of an antenna.
EFFECT: improved detectability of the reflected signal on the background of reflections from local objects.
