Radar scattering properties of bicycles at 77 GHz

Collision avoidance systems are becoming a common a standard safety feature in newer or future cars. Some radars operating at 24 GHz have been successfully used in parking, lane changing, and blind spot detection. Newer 76-78 GHz radars are being developed and tested by car makers for their superior range and resolution. However, using cost effective vehicular radars in reliably detecting pedestrian and bicyclist with low false alarm rate still poses challenging due to many possible variations of these targets as well as the presence of other road objects. This paper focuses on studying the radar scattering characteristics of common bikes in stationary in the 76-78 GHz band with a goal of being able to design a more effective bicycle detection radar and detection algorithm.
