Abstract
In this paper we present data from a new low THz radar. We show that the resolution of the raw data is limited by range independent phase error which is generated by multiple reflections in the receiver cable. The transmitted waveform is found to be extremely linear. The phase gradient algorithm is used to remove the phase error. The resolution of the corrected data is illustrated by imaging a metal trolley to reveal features in a cm scale.
