Dual polarisation systems, imaging systems and complementary systems operating at cm/mm/IR/EO wavelengths have been singled out for future research, after a brief description of the roles of current mm-wave systems. The underlying aims have been an enhancement of the performance of present systems as well as the extension of their capabilities during inclement weather. The scene is now set for widespread, high volume, commercial applications of mm-wave systems. These systems derived considerable benefits from R&D undertaken for military systems and the MIMIC program. Communication systems are also destined to attract significant funds during this decade.
