Abstract
Un câble de recherche géophysique (16) comprend un amplificateur de signal (20) branché entre deux électrodes (18) espacées sur la longueur du câble de recherche géophysique (16) (les électrodes (18) étant reliées à l'amplificateur de signal (20) par une première paire de conducteurs (17)), et un amplificateur de bruit (30) relié à une deuxième paire de conducteurs (27) disposée de manière sensiblement parallèle à la première paire de conducteur. Le câble de recherche géophysique (16) comprend en outre un circuit de combinaison qui combine un signal de bruit fourni par l'amplificateur de bruit (30) avec un signal de capteur fourni par l'amplificateur de signal (20) afin de procurer un signal de capteur avec une composant de bruit réduite.
