Title (EN) HIGH RESOLUTION RANGING APPARATUS AND METHOD USING UWB
(FR) APPAREIL ET PROCEDE DE TELEMETRIE A HAUTE RESOLUTION PAR BANDE ULTRALARGE
Abstract: front page image
(EN)Provided is a high-resolution distance ranging apparatus using an ultra-wideband (UWB) communication. The apparatus includes: a first spectrum analyzer for extracting a frequency component corresponding to multipath time delay from a reception signal; a second spectrum analyzer for acquiring a noise subspace of the extracted frequency component and extracting a frequency component where maximum power is located from a frequency spectrum based on the noise subspace; a time of arrival (TOA) extractor for extracting TOA based on the frequency component where maximum power is located.
(FR)L'invention concerne un appareil de télémétrie à haute résolution utilisant une communication à bande ultralarge (UWB). L'appareil comprend: un premier analyseur de spectre destiné à extraire une composante de fréquence correspondant à une temporisation multivoie d'un signal de réception; un second analyseur de spectre destiné à acquérir un sous-espace de bruit de la composante de fréquence extraite et à extraire une composante de fréquence dans laquelle une puissance maximum est localisée à partir d'un spectre de fréquence, sur la base du sous-espace de bruit; un extracteur de temps d'arrivée (TOA) destiné à extraire le TOA sur la base de la composante de fréquence dans laquelle se trouve la puissance maximum.
