Title (EN) UTILITY LOCATING SYSTEMS, DEVICES, AND METHODS USING RADIO BROADCAST SIGNALS
(FR) SYSTÈMES, DISPOSITIFS ET PROCÉDÉS DE LOCALISATION DE SERVICE PUBLIC À L'AIDE DE SIGNAUX DE DIFFUSION RADIO
Abstract:
(EN) Systems, devices, and methods for locating buried conductors using ambient electromagnetic signals, such as AM or other broadcast signals, are described. A buried utility locator may include a plurality of spatially separated antenna arrays, a receiver circuit coupled thereto, and a processing element programmed to process measurements of ambient electromagnetic signals and associated electromagnetic signals radiated from current induced in the buried conductor from the ambient signals to determine information about the buried conductor.
(FR) L'invention concerne des systèmes, des dispositifs et des procédés pour localiser des conducteurs enterrés à l'aide de signaux électromagnétiques ambiants, tels que des signaux de diffusion en modulation d'amplitude (AM) ou autres. Un localisateur de service public enterré peut comprendre une pluralité de réseaux d'antennes spatialement séparés, un circuit récepteur couplé à ces derniers, et un élément de traitement programmé pour traiter des mesures de signaux électromagnétiques ambiants et de signaux électromagnétiques associés rayonnés par un courant induit dans le conducteur enterré à partir des signaux ambiants pour déterminer des informations concernant le conducteur enterré.
