GEAR FOR VIBRO-SEISMIC PROSPECTING Russian patent published in 1994 - IPC

FIELD: seismic prospecting. SUBSTANCE: gear for vibro-seismic prospecting includes correlator 4, inverse filter with spectrum analyzers 1, 2, 5, complex number multiplier 3 and divider 6. Correlator performs function of correlation convolution of recorded vibro-seismic signals with reference vibro-seismic development. As a result of multiplication of complex spectra of reference and vibro-seismic signals in multiplier 3 function inverse to transfer function of filter is obtained. This allows correlation background on correlogram to be suppressed. EFFECT: improved operational efficiency. 1 dwg
