FACILITY FOR SEARCH WITH USE OF DELAY OF SIGNALS WITH SUDDEN FREQUENCY CHANGE Russian patent published in 2003 - IPC

Abstract RU 2207721 C2

FIELD: radio engineering, communication systems with sudden change of frequency. SUBSTANCE: given facility realizes method of search during which duration of pulses across output of mixer formed by narrow-band interference is markedly greater than that of pulses of legitimate signal which makes it feasible to suppress narrow-band noises practically without distortion of pulse of legitimate signal thanks to employment of limitation and procedures of direct and inverse Fourier transform. EFFECT: increased noise immunity to narrow-band noises and as result diminished probability of false alarms. 4 dwg
