“…The detection of the various obstacles by an UWB system is based on the transmission and reception of brief duration pulses, of the order of a few Pico or nanoseconds [7], which requires a specific signal processing at a reception to properly exploit the reflected signals [8] and extract the maximum amount of information. In order to develop a UWB radar [9] system capable of detecting targets in urban areas, one of the main difficulties is related to the complexity of the propagation environment induced by the obstacles present in the scene, and generally, the target is not in the line of sight of the radar, which complicates the task more and more.…”

<span>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.</span>
