Abstract

Un système dacquisition et de traitement de signaux de champ électrique de basse fréquence, comme des signaux magnétotelluriques, associés à des structures géologiques en sous-surface. Au moins une antenne de ligne capacitive acquiert les signaux. Un circuit de rétroaction augmente limpédance dentrée pour les signaux pour réduire la fréquence à laquelle latténuation du signal se produit.
