VIBROSEISMIC SURVEY METHOD Russian patent published in 1998 - IPC

Abstract RU 2102776 C1

FIELD: vibroseismic survey. SUBSTANCE: method involves use of unequal-polarity train of short identical frequency-modulated signals whose code function provides for elimination of abnormal expansion of correlation background caused by periodic repetition of sweeps from useful record intervals on correlograms. EFFECT: reduced resonance effect in building structures and their improved safety during vibroseismic survey.
