enhanced channel for measurement of aircraft radial velocity with use of intermodal frequencies and modified block of deflectors for combined laser system

摘要

An enhanced channel for measurement of aircraft radial velocity with use of intermodal frequencies and modified block of deflectors for 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, photodetector, broadband amplifier, multifunction information block, with σ – input of signal of measured aircraft circumferential velocity (attitude rates), resonance amplifiers adjusted to the corresponding intermodal frequencies, mixing circuits, filters, phase-locked-loop frequency control on the intermodal frequency, control generator, reference generator with conversion frequency EMBED Equation.3 , pulse formers, AND circuit, pilot pulse former, counter, decoder, electronic computing machine and EMBED Equation.3 - input of reference frequency EMBED Equation.3 from transmitting laser (Lp + LMS FDM). Additionally an optical-electronic module is incorporated, this is formed of television and infrared channels.
