Paper Abstract

This paper reviews the feasibility and requirements of scanning passive millimetre wave imaging systems based on the latest electronic technologies. The sensitivities, bandwidths and field-of-views of imaging radiometers are examined on the basis of large numbers (several hundreds) of distributed antennas and receivers. Transfer functions and point spread functions, of minimum redundant arrays for imaging, are calculated and the effects of phase stability assessed. Possible future directions of passive millimetre imaging, enabled by the storage of pre-detection radiometric data, are highlighted..
