A Near-Millimeter Wave interferometric radar

2013 IEEE Radar Conference (RadarCon13), 2013
Due to the paucity of high-power sources along with strong electromagnetic absorption by water vapor at frequencies between ~100 GHz and ~10 THz, there are very few radar systems operating in the terahertz range of the spectrum. Source technology, however, is improving, thus facilitating radar systems operating in this gap.

On energy potential of millimeter-wave radar

Third International Kharkov Symposium 'Physics and Engineering of Millimeter and Submillimeter Waves'. MSMW'98. Symposium Proceedings (Cat. No.98EX119), 2002
One of the most serious problems of a short-pulse millimeter (MM) wave radar is deficit of its energy potential. The radar range upper limit of about a few kilometers is caused mostly by two factors: (1) low energy of transmitting signal pulses restricted by generator overheating or breakdown of waveguiding structures; and (2) decreasing of signal ...
