A channel for measurement of radial velocity of aircrafts with multichannel longitudinal mode selector and additional scanning for laser information and measuring system of a launch-site test complex comprises a control element, a block for control of deflectors, pumped laser (Lp), multichannel longitudinal mode selector (MLMS), block of deflectors, transmitting optics, receiving optics, photodetector, broadband amplifier, information block, resonance amplifiers adjusted to respective frequencies of inter-mode beats, pulse formers, circuit AND, counter, mixers, filter, former of measuring pulses, decoder (DC), phase automatic frequency control at frequency of inter-mode beats, control generator, reference generator with support frequency &Dgr;&ngr;&pgr;, block for representation of measuring information on radial velocity R' of the aircraft and 6&Dgr;&ngr;– input of reference frequency (6&Dgr;&ngr;) from transmitting laser (Lp+MLMS). After DC instead of electronic-digital computing machine a computer is included. |
