A channel for measurement of radial velocity of aircrafts with use of frequencies of inter-mode beats and capability of aircraft search and identification for a range test complex includes a control element, deflector control unit, pumped laser (Lp), longitudinal-mode selector with multi-frequency multiplexing (LMS MFM), modified block of deflectors, transmitting optics, receiving optics, photo-detector, broadband amplifier, multi-functional information block with b – input of the signal of tangent velocity (angular velocities) of the aircraft that is measured, resonance amplifiers adjusted to respective frequencies of inter-mode beats, pulse formers, circuit AND, counter, mixers, filter, former of measuring pulses, decoder (DC), phase frequency auto-control at frequency of inter-mode beats, control generator, reference generator with support frequencyand- input of reference frequencyfrom transmitting laser (Lp+ LMS MFM). After the DC instead of electronic-digital computing machine and block for displaying information on radial velocity R' of the aircraft an electronic computer is included. |
