Abstract
With the rapid development of science and technology of intelligent transportation, Frequency Modulated Continuous Wave (FMCW) radar sensor has been widely used in automotive auxiliary driving. This paper presents a method to obtain parameters of obstacles ahead a vehicle. Firstly, the signal processing is applied to detect and analyze the moving obstacle to get its range, speed and Doppler shift. Then, a spatial model is set up for the height detection of the obstacle. Finally the feasibility of the introduced method is demonstrated through simulation by using FMCW radar sensors which are mounted on a vehicle. This method of obstacle detection may be applied on safety driving assistant.
