Abstract

L'invention concerne un procédé permettant de déterminer l'orientation d'un récepteur électrique et magnétique déployé à distance, consistant: à mesurer des données électriques et magnétiques en réponse à une source active appliquée; à traduire les données en composants en ligne (composante x) par rapport au dipôle électrique du récepteur et orthogonaux (composante y) par rapport à celui-ci; à transformer les données à partir du domaine temporel à un domaine fréquentiel et à les normaliser; et à calculer l'angle de rotation ϑ entre la direction du dipôle source et le dipôle du récepteur.
