Hi all,
I am translating a geological documentation and came across this term but can't find a French equivalent anywhere...
The sentence is
To identify low-power scattered waves in the man-made seismic wave field, synchronous stacking of signals of scattered waves with the stacking fold of 104, suppression of reflected waves via special observation geometry called the Side-View Seismic Locator as well as proprietary focusing transformation algorithms (SFT) are utilized.
My attempt
Pour identifier les ondes diffusées de faible puissance dans le champ d'onde sismique fait par l'homme, l'empilement synchrone de signaux d'ondes diffusées avec ?????? de 104, la suppression des ondes réfléchies par la géométrie d'observation spéciale appelée Side-View Seismic Locator ainsi que les algorithmes exclusifs de Focusing Transformation (SFT) sont utilisés.
Merci pour votre aide

"Stacking Fold
Stacking fold is the number of field traces that are summed during data processing to create a single image trace positioned at the center of each bin.
At any stacking bin coordinate, the stacking fold inside the bin varies with depth. Referring to figure 2, when a stacking bin is centered about a deep reflection point B, the stacking fold is a maximum at depth B because the largest number of source and receiver pairs can be utilized to produce individual reflection field traces inside the bin.
The number of source-receiver pairs that can contribute to the image at B is typically confined to those source and receiver stations that are offset horizontally from B a distance that is no larger than depth Z2 to reflection point B."

Note from asker:
| As always, thank you... But should I write "avec un sommation de couverture sismique de 104" ... ? |
| I mean "avec une sommation en couverture multiple de 104"... |
