In this paper low-THz FMCW radar is introduced for automotive applications. Ability to produce a short-range high resolution image of the road ahead of the vehicle under any weather or terrain conditions is a considerable advancement for the automotive use. The 150 GHz FMCW radar requirements and specifications are discussed in this paper. The imaging performance of the 150 GHz radar in a real road scenario is demonstrated; the experimental results of the 150 GHz FMCW and a 30 GHz stepped frequency radar are presented and compared to each other.
