A channel for measurement of radial velocity of aircrafts with multichannel longitudinal mode selector for laser information and measuring system of a launch-site test complex includes 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 frequency self-tuning at frequency of inter-mode beats, control generator, reference generator with support frequency &Dgr;vblock for representation of measuring information on radial velocity R' of aircraft and 6&Dgr;v– input of reference frequency (6&Dgr;v) from transmitting laser (Lp+MLMS). After DC instead of electronic-digital computing machine a computer is introduced. |
