DEVICE FOR AUTOMATIC SEARCH FOR RADIO STATIONS Russian patent published in 1997 - IPC

FIELD: radio engineering, radio dispatching points that monitor and analyze signal situation. SUBSTANCE: device for automatic search for radio stations has former 1 of controlling signals, generator 2 of reference frequencies, receiver 3 and signal detector 4 which includes former 5 of clock frequency, unit 6 extracting signal of cyclic frequency, unit 7 storing signals of clock and cyclic frequencies , comparator 8 and indicator 9. Realization of invention leads to enhanced probability of detection of working communication channel in case of frequent changes of working frequencies of watched radio station since decision on belonging of signal on i-th fixed frequency of radio station of interest is made in case of agreement of stored pulses in time and frequency to corresponding starting clock and cyclic frequencies of received signal on each i-th fixed frequency. EFFECT: enhanced probability of detection of working communication channel. 11 dwg
