A channel for measurement of radial velocities of aircrafts with modified longitudinal-mode selector and capability of formation and processing the aircraft image for laser information and measuring systems of a range test complex comprises a control element, a block for control of deflectors, pumped laser (Lp), modified longitudinal-mode selector (MLMS), modified block of deflectors, transmitting optics, receiving optics, photodetector, broadband amplifier, modified information block, resonance amplifiers adjusted to respective frequencies of inter-mode beats, pulse formers, AND circuit, counter (C ), mixers, filter, former of measuring pulses, decoder, phase automatic frequency control at frequency of inter-mode beats, control generator, reference generator with reference 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 the transmitting laser (Lp+MLMS). After the C instead of electronic-digital computing machine an electronic computer is included. |
