Least-square Attenuation of Reverse Time Migration Artifacts

SUMMARY Reverse time migration artifacts occur when diving waves, headwaves or backscattered waves cross-correlate. These events are particularly strong where high velocity contrasts exists. Simpleminded ltering of the nal image can lead to good results, but might compromise the integrity of the signal of interest. A better technique consists in applying a least-square ltering with prediction-error lters, a method traditionally used for signal/noise
