FIELD: radio navigation, namely methods and devices for measuring radial speed of moving object.
SUBSTANCE: to exclude error of measurement of radial speed, caused by instability of frequency of Doppler speed meter transmitter, generation of time interval, during which Doppler frequency impulses are counted, is performed by dividing frequency of transmitter by means of fast action frequency divider.
EFFECT: increased precision when measuring radial speed during usage of simplified transmitter, which reduces costs of Doppler speed meter.
