Abstract

L'invention concerne un dispositif de mesure en forage pour recevoir des signaux radar comportant un ensemble d'antenne qui fait partie d'un corps de sonde et dont le diagramme directionnel permet, en relation avec un appareil de traitement relié à l'ensemble d'antenne, de dériver des valeurs de mesure caractérisant la direction d'incidence à partir des signaux reçus; il est prévu une bobine rectangulaire à cadre (2) dont l'axe longitudinal coincide sensiblement avec l'axe longitudinal du corps de sonde (1) et dont des parties de conducteurs paralléles à l'axe longitudinal (11) sont disposées sur la surface extérieure du corps de sonde.
