FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering and can be used in short-range radar systems. Specified result is achieved due to the fact that the measuring device has a rectangular high-frequency pulse generator, receiving and transmitting antennas, phase detector, switch, two mixers, local oscillator and phase incursion indicator, connected to each other in a certain manner.
EFFECT: technical result consists in the increased accuracy of object speed measuring by measuring the phase incursion.
