In this paper the requirements for low-THz automotive sensors are presented with the focus on THz imaging of the terrain in front of the vehicle. Initial imaging performance at 150 GHz radar is demonstrated and a planned extension using an advanced 300 GHz radar system is described. Antenna requirements for these systems are discussed.
A cryogenic based primary noise standard specifically suited for THz applications is described. Key features which offer improved THz performance are described. The standard consists of a common cryogenic vessel with replaceable waveguide antenna assemblies and a computer controlled interface.
