Abstract

L'invention concerne des procédés de reconnaissance géophysique. Un signal de commande appliqué à un transducteur provoque l'emission d'ébranlements qui sont captés par des détecteurs pour obtenir des informations sur des discontinuités du sous-sol. Le signal de commande est combiné avec plusieurs fractions se succédant dans le temps et dont au moins deux fractions immédiatement successives sont soumises, quant à leur fréquence et/ou leur amplitude et/ou à leur phase, à différentes fonctions liées au temps. Application : prospection géophysique.
