Abstract

L'invention concerne un agencement d'émetteur modulé haute fréquence destiné à être utilisé dans l'arpentage géophysique. L'agencement d'émetteur comporte un émetteur de commutation relié fonctionnellement à une boucle d'émetteur, l'émetteur de commutation étant conçu pour commander une circulation de courant électrique dans la boucle d'émetteur. L'émetteur de commutation reçoit une tension d'entrée et produit une tension de sortie pour provoquer la circulation de courant dans la boucle d'émetteur, la tension de sortie étant régulée par modulation d'impulsions en largeur de la tension d'entrée afin de produire une forme d'onde de courant souhaitée dans la boucle d'émetteur.
