RECEIVER OF RADIO-IMPULSE SIGNALS WITH FREQUENCY-TIME ENCODING

摘要

FIELD: electric communications, possible use in receivers of radio-impulse signals with frequency-time encoding in radiolocation with active response, radio control and communication.;SUBSTANCE: receiver of radio impulse signals with frequency-time encoding consists of serially connected high frequency amplifier, mixer, to second input of which heterodyne is connected, logarithmic amplifier, to output of which narrowband channels are connected in parallel, consisting of serially connected narrowband filter, detector and video amplifier, in each channel connected to output of video amplifier in parallel are inverter of polarity, adder and key cascade, to second input of the latter outputs of inverters of adjacent channels are connected, and if key cascade of one of channels is in closed state, then key cascades of other channels are in open state.;EFFECT: preservation of information about signal amplitude and provision of frequency selectiveness of adjacent channels under conditions of change of signals in large dynamic spectrum (60-80 decibels) during receipt of signals with frequency-time encoding with overlapping spectrums.;5 dwg
