METHOD AND DEVICE FOR GEOPHYSICAL COMBINED PROSPECTING Russian patent published in 1994 - IPC

FIELD: radiolocation. SUBSTANCE: radiosignals and seismic-acoustic signals are irradiated. Radio- and echo-signal received are transformed into frequency of seismic-acoustic echo-signals. Then all the echo-signals are amplified, filtered, weighed and processed preliminary when using the same hard- and software. During period of preliminary processing the products of echo-signals are computed from the sequent excitations and 5-30 products in set are added depending on rate and purposes of inventions. To improve depth of prospecting the mismatch correction is brought at the stage of signal processing accounting with difference of seismic-acoustic signals and radiosignals from standard level. Moreover, time signal between two pulse effects is adjusted to be equal to 0.25-1 period. Device has stroboscope 3, analog duct 6 provided with processor 7 and tracking frequency converter 4. EFFECT: improved efficiency; improved precision. 4 cl, 2 dwg
