An enhanced channel for measurement of slant range distance to aircrafts with use of frequencies of inter-mode beats for a range test complex includes a control element, block for control of deflectors, pumped laser, longitudinal mode selector with frequency-division multiplexing, prisms for the frequency of inter-mode beats &Dgr;&ngr;, block of deflectors, switch for the frequencies of inter-mode beats &Dgr;&ngr;and 2 &Dgr;&ngr;, transmitting optics, receiving optics, photo-detectors, broadband amplifier, information block with advanced facilities with b – input of signal of measured tangent velocity (angular velocities) of the aircraft, resonance amplifiers adjusted to respective frequencies of inter-mode beats, pulse formers, trigger "1"|"0", AND circuits, counters (Co), filter with set pass band, detector, differential optics, amplifier, filter, differentiating circuits and rectifiers. After the Co instead of electronic-digital computing machine and block for representation of information on slant range R to the aircraft an electronic computer is introduced. |
