Abstract

La présente invention concerne un dispositif et un procédé permettant une cartographie d'éléments à l'origine de modifications locales du champ magnétique terrestre. L'invention concerne plus particulièrement un dispositif et un procédé de cartographie d'éléments à l'origine de modifications locales du champ magnétique terrestre qui évitent les inconvénients de l'état antérieur de la technique, et qui, contrairement aux cartographies 2D du champ magnétique terrestre avec des systèmes de type SQUID, permettent de déterminer les profondeurs et les dimensions concrètes des objets à détecter. À cet effet, le dispositif comporte des capteurs de haute sensibilité servant à mesurer le gradient du champ magnétique terrestre, une unité de géolocalisation permettant de déterminer la position du capteur dans le champ de mesure à cartographier, un ordinateur à mémoire, ainsi qu'une unité support mobile amagnétique à laquelle sont fixés les capteurs, l'unité de géolocalisation et l'ordinateur à mémoire. Le dispositif comprend au moins deux capteurs orientés dans la même direction et disposés l'un au-dessus de l'autre avec un écartement vertical et servant, d'une part à mesurer le gradient local du champ magnétique, et d'autre part à enregistrer simultanément les signaux de tous les capteurs et de l'unité de géolocalisation.
