An enhanced channel for measurement of aircraft radial velocity with use of intermodal frequencies and modified block of deflectors for a test range complex comprises a control element, unit for control of deflectors, pumped laser (Lp), longitudinal mode selector with frequency division multiplexing (LMS FDM), modified block of deflectors, transmitting optics, receiving optics, photodetectors, broadband amplifier, multifunction information block with &sgr;– input of signal of measured aircraft circumferential velocity (attitude rates), resonance amplifiers adjusted to the corresponding intermodal frequencies, pulse formers, AND circuit, counter, mixing circuits, filter, monitoring pulse former, decoder (DC), phase-locked-loop frequency control on the intermodal frequency, control generator, reference generator with conversion frequencyand- input of reference frequencyfrom transmitting laser (Lp + LMS FDM). Next after the DC instead of electronic-digital computing machine and the unit for displaying information on aircraft radial velocity R' an electronic computer is included. |
