AUTOMATIC RADIO-STATION SIGNAL SEARCH DEVICE Russian patent published in 2007 - IPC H03J7/18 

FIELD: radio engineering; radio-supervision monitoring centers for analyzing signal situation in region.

SUBSTANCE: proposed automatic radio-station signal search device that can be used for automatic search and detection of signals from radio stations being monitored which permanently and frequently change their operating frequencies and operate in environment of complex noise and more than one signals from different stations within high-frequency band has control signal generator, reference-frequency unit, receiver with antenna, and signal detector; the latter incorporates driven clock frequency shaper, clock-frequency shaper memory unit, delay shaping unit, phase-difference level shaper, threshold level shaper, comparison unit, and display.

EFFECT: enhanced probability of communication channel detection in high-frequency band.
