A channel for measurement of radial velocity of aircrafts with modified longitudinal-mode selector and capability of aircraft identification for laser information and measuring system of a range test complex comprises a control element, block for control of deflectors, pumped laser (Lp), modified longitudinal-mode selector (MLMS), modified block of deflectors, transmitting optics, receiving optics, photodetector, broadband amplifier, multi-functional information block with b – input of signal of tangent component (angular velocities) of the aircraft (A) that is measured, resonance amplifiers adjusted to respective frequencies of inter-mode beats, pulse formers, AND circuit, 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;v&pgr;, block for representation of measuring information on radial velocity R' of the A and 6&Dgr;v– input of reference frequency (6&Dgr;v) from transmitting laser (Lp+MLMS). After the DC instead of electronic-digital computing machine an electronic computer is included. |
