1 76 GHz 76-GHz Millimeter-Wave Radar for Automotive Use 150 m Abstract Given the effectiveness of new vehicle control systems including Pre-Crash Safety systems in reducing traffic fatalities or preventing traffic jams, such systems are being examined for reducing collision damage. Systems that detect vehicles and obstacles to the rear and side, as well as ahead have already been marketed, and soon systems that detect objects in all directions will be developed. Such systems employ millimeter-wave radar, given its weather resistance and compact structure.
2 Long-range radar offers superior angle accuracy and can measure distance and relative velocity beyond 150 meters. Compact, short-range radar is characterized by compact size, wide-angle detection, and high-speed processing. We believe that millimeter-wave radar will find expanded applications in various systems through improved sensing performance and operation in conjunction with various other sensors in the future. This paper introduces some examples of development and describes our future challenges.
