Abstract :
A small signal processing computer has been interfaced with to the single channel seismic reflection system in use at Atlantic Geoscience Centre (AGC). In this way real time dereverberation, stacking and display of data, particularly in the deep ocean and on the continental slopes can be carried out. Time corrections applied to the signal make bottom reverberations nearly periodic. This dramatically improves the effectiveness of the simple Backus filter. Examples of data before and after processing are presented.
