La détection de cavités en milieu urbain est importante pour prévenir différentes causes d'accidents liés à des possibles effondrements. Les cavités sont aussi des cibles d'intérêts pour les archéologues, car les cavités oubliées sont de potentielles sources de matériel révélant des usages passés. Ces cavités sont de tailles différentes, d'origine anthropique ou non, en milieu extérieur ou sous des bâtiments. Leur taille, ainsi que les propriétés physiques du milieu extérieur dans lequel elles se situent, permettent l'utilisation de différentes méthodes géophysiques. Nous nous sommes concentrés sur l'utilisation de deux méthodes géophysiques, le radar de sol et la tomographie par mesures de résistivité électrique, pour localiser et détermin...
