Abstract
Use of sub-THz radar for automotive applications brings many potential game changing advantages, in terms of sensor size and imaging capabilities. We discuss the fundamentals governing these advantages and then focus on the potential to achieve increased azimuth resolution through processing techniques such as synthetic aperture radar and Doppler beam sharpening at sub-THz carriers, in comparison to current automotive frequencies. Examples of theoretical achievable resolutions are given for the automotive scenario and experimentation is carried out showing theoretical resolutions are achievable in ideal conditions. We highlight the factors that may affect the achievable resolutions and thus research areas that need to be further studied for sub-THz image formation and briefly discuss the current state of hardware development.
