QUASI-OPTIMAL COMB FILTER FOR SEQUENCE OF WIDEBAND AND ULTRA-WIDEBAND COHERENT RADIO PULSES WITH COMPRESSION OF SIGNAL SPECTRUM

摘要

FIELD: radio engineering, communication.;SUBSTANCE: device contains parallel-band pass filters matched to the duration of this sequence, phase shifters and an adder. In addition, the device comprises mixers, heterodynes, and a reference signal generator. In this case, the input signal is fed to the first inputs of the mixers, and the second inputs are connected to the outputs of the different-frequency heterodynes. The inputs of the heterodynes are connected to the output of the reference signal generator. The outputs of the mixers are connected to the inputs of the bandpass filters. The outputs of the bandpass filters are connected to the inputs of the phase shifters, and the outputs of the phase shifters are connected to the inputs of the adder.;EFFECT: obtaining a high quality factor of the comb filter.;5 dwg
