Car detection using curved mirrors by automotive millimeter wave radar

This paper addresses the theme of expansion in the range of uses of an automotive radar. In recent years, ITS has been researched actively in order to prevent accidents. Use of a radar could be considered as one of the collision prevention technologies, and a small portion of vehicles are equipped with automotive radars now. Although the automotive radar uses laser or millimeter wave, the radar which used the millimeter wave is becoming mainstream. One of the features of a millimeter wave is that it tends to travel straight. Therefore it can be used only within a line of sight. Here, we propose a car detection using reflection of curved mirrors as the system which can detect cars at low visibility intersections. It is shown in this paper, the possibility of the system we proposed by received power analysis and experiment.
