    Abstract

    Imaging at submillimetre-wave frequencies is of considerable interest thanks to potentially superior performance at longer stand-off ranges in comparison to mm-wave imaging thanks to improved angular resolution. In this paper we discuss the performance of multispectral passive imaging system centred around 250, 400 and 750 GHz. Multi-band imagery is interesting given its potential for rudimentary materials differentiation, a capability that would substantially benefit e.g. security imaging applications. The passive imaging activities are complemented by activities towards developing rapid electronic beam steering capability for imaging submm-wave radars. Results from two project aiming at constructing such beam steering systems at 120 GHz and at 650 GHz are presented.
