Performance Comparision of Vehicular Radar System between On-Road and Tunnel Space

摘要

Recently, vehicular radar systems are widely adopted to monitor various traffic accident situations on the road. Although the radar provides real-time object detection and high accuracy, it suffers from severe performance degradations when it is surrounded by unexpected obstacles such as traffic barrier and road side wall. In this paper, in order to analyze these problems, we conduct performance comparisons of the vehicular radar system between open road space and enclosed tunnel space. Through the experiment results, we confirm that the radar system is highly affected by neighboring structures and buildings. In addition, we also reveal that the performance of the radar system can be improved by tuning the view angle and height when it is installed.
