CHANNEL FOR MEASUREMENT OF RADIAL VELOCITY OF AIRCRAFTS WITH USE OF INTERMODAL FREQUENCIES AND CAPABILITY OF SEARCH, FORMATION AND PROCESSING THE AIRCRAFT IMAGE FOR A COMBINED LASER SYSTEM

摘要

A channel for measurement of radial velocity of aircrafts with use of intermodal frequencies and capability of search, formation and processing the aircraft image for a combined laser system 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, photo-detector, broadband amplifier, modified information block, resonance amplifiers adjusted to respective intermodal frequencies, mixers, filters, phase-locked loop system at the intermodal frequency, control generator, reference generator with conversion frequency Δνм, pulse former, AND gate, former of measuring pulses, counter, decoder, electronic computing machine, and σΔ(м - input of reference frequency (σΔ(м оп) from transmitting laser (Lp + LMS FDM). Additionally an optical-electronic module is incorporated, this comprises television and infrared channels.
