High order statistic receiver applied to UWB radar

To enhance road safety, many studies have been carried out on on-board collision avoidance system. The goal of these systems is to keep the vehicle at a safe distance from any obstacle in front of it. This paper deals with study of a collision avoidance system based on radar techniques which employs a new technology called ultra wide band (UWB). The exploit of this technology for the radar makes it possible to have a very good precision and a capacity to detect several obstacles at the same time and even to make the difference between them thanks to their signature and all that with low powers so low energy consumption. This paper presents a detection method of road obstacles using high order statistics (H.O.S.). The main advantage in this application is to decrease the noise effect and to enhance the detection performances comparing to the classical correlation.
