SAFIRE: A close range fast scanning high resolution millimetre wave radar for public education

The millimetre wave group at the University of St. Andrews is constructing a fast scanning, high resolution 94 GHz FMCW radar named SAFIRE. The radar is designed to provide real time imagery of close range scenes both indoors and outdoors as part of a programme for public education on the specific topic of millimetre wave imaging. We present an outline of the design motivation and performance required for fast sampled close-range radar in a cluttered environment.
