Automatic target detection and localization using ultra-wideband radar
The pulse ultra-wide band (UWB) radar consists of switching of energy of very short duration in an ultra-broadband emission chain, and the UWB signal emitted is an ultrashort pulse, of the order of nanoseconds, without a carrier. These systems can indicate the presence and distances of a distant object, call a target, and determine its size, shape, speed, and trajectory. In this paper, we present a UWB radar system allowing the detection of the presence of a target and its localization in a road environment based on the principle of correlation of the reflected signal with the reference and the determination of its correlation peak
ETUDE DES FORMES D’ONDES D’UN RADAR ULB DANS LE CONTEXTE VEHICULAIRE
Le principal problème rencontré pour l’utilisation de la technologie ULB est le choix de la forme d’onde adéquate en fonction de l’application envisagée. Dans cet article, nous présentons le radar ULB utilisé dans le contexte V2V (Vehicle to Vehicle) et les simulations effectuées sous Matlab dans le but de choisir la forme d’onde la plus adéquate au système étudié. Les résultats de simulation nous ont permis de déduire que l’impulsion monocycle donne les meilleurs performances en termes de précision par rapport au polynômes de Geganbauer et d’Hermite
