SEISMIC CORRELATIVE OBJECT BEARING FINDER Russian patent published in 2003 - IPC

FIELD: intruder alarms; finding bearings to objects detected in vicinity of guarded line. SUBSTANCE: bearing finder that functions to count number of objects in group target and to classify objects detected uses scattered passive location method to perform its function, main information sign for determining direction to object being mutual signal correlation function for two signal processing channels. Decision on azimuth to object is taken according to signal delay time and signal delay measurement is equivalent to directivity pattern control of seismic antenna system. EFFECT: enhanced self-descriptiveness of seismic detectors; provision for spatial signal selection in noise background. 1 cl, 2 dwg
