PCT No. PCT/FR95/01231 Sec. 371 Date May 22, 1996 Sec. 102(e) Date May 22, 1996 PCT Filed Sep. 25, 1995 PCT Pub. No. WO96/09562 PCT Pub. Date Mar. 28, 1996The invention relates to a seismic prospection method in which a seismic disturbance is generated in the sub-soil and sensors are used to pick up seismic data, the seismic data being processed to deduce useful information concerning the geology of the sub-soil, the seismic data containing a signal y0 that is to be isolated, said signal y0 being present in the seismic data embedded in an additive signal. The method comprises the steps consisting in: 1) for alpha given integer p, computing a prediction error filter a having p coefficients and providing best cancellation of the signal y0; 2) applying the self-deconvoluted prediction error filter to the seismic data to obtain filtered data in which the signal y0 is absent; and 3) subtracting the filtered data from the initial data to obtain processed data containing the signal y0 without the additive signal. |
