Channel for measurement of redial velocity of aircrafts with use of frequencies of inter-mode beats and additional scanning includes control element, block for control of deflectors, laser with pumping (Ln), transfer optics, pulse formers, circuit “and”, counter, mixers, filter, firmer of measuring pulses, decoder, phase auto-adjustment of frequency and frequency of inter-mode beats, control generator, support generator with support frequency &Dgr;&ngr;, computer, block for representation of measuring information on radial velocity R' of aircraft. After Ln there is additionally included selector of long modes with multi-frequency separation of channels (SPM BRK) and 6&Dgr;&ngr;– input of support frequency (6&Dgr;&ngr;) from transmission laser (Ln + SPM BRK), and modified block of deflectors. |
