Abstract

The development of signal processing system on urban transit application using 77 GHz FMCW radar J.-H. Baek, J.-B. Wang, Y.-S. Byun & H.-J. Park KRRI (Korea Railroad Research Institute), South Korea Abstract Many companies and laboratories explore the potential use of ranging sensors for reducing the occurrence of accidents in real environment. Most of the sensors under investigation utilize the FMCW (Frequency Modulated Continuous Wave) waveforms. The automotive environment presents to the FMCW radar sensor a multitude of moving and fixed targets and the sensor must detect and track only the targets, which may pose a threat of collision or passenger accident. The sensor must function accurately in the presence of background echoes generated by moving and fixed targets, ground reflections, atmospheric noises, including rains, fog, and, snow and noise generated within the receiver. False detection of the desired target in this environment may issue false alarms. This may b
