METHOD OF REDUCTION OF NOISE LEVEL OVER SEISMIC ROUTES

摘要

control over noise from foreign sources of elastic vibration while conducting sea seismic operations. SUBSTANCE: permissible threshold value of amplitude in time window of reference route is compared with amplitude characteristics of seismogram of analyzed route in same window. Scalar coefficient not equal to zero is used in given time window for conversion of analyzed route if its amplitude inside time window leaves limits of threshold values of amplitude characteristics. EFFECT: effective suppression of coherent noise without attenuation of legitimate signals. 40 cl, 5 dwg
