Title
(EN) UNDERGROUND PIPE LOCATING SYSTEM
(FR) SYSTEME DE LOCALISATION DE TUYAUX SOUTERRAINS
Abstract
(EN)
A system for locating and identifying underground pipes, utilizing a ground-probing radar. The ground-probing radar system includes an antenna module and a transmit/receive sub-system. The system also includes a digital signal processing sub-system for processing the received signal to extract data corresponding to detected differences in dielectric constant and a master controller. The system still further includes a positioning sub-system, a display sub-system, a user interface and a data storage mechanism, display data and said operating parameters.

La présente invention concerne un système de localisation et d'identification de tuyaux souterrains grâce à l'emploi d'un radar qui explore le sol. Ce système comprend un module à antenne et un sous-système émetteur-récepteur. Il comprend aussi un sous-système de traitement de signaux numériques servant à traiter le signal reçu pour en extraire des données correspondant à des différences détectées de constante diélectrique, et une unité de commande maîtresse. Il comprend également un sous-système de positionnement, un sous-système d'affichage, une interface d'utilisateur et un mécanisme de stockage de données ainsi que des données d'affichage et des paramètres de fonctionnement.
