Technology for submillimeter wave remote sensing

NASA's sub-mm wave technology development program addresses emerging possibilities in spaceborne sensor design for what is one of the few unexplored regions of the spectrum, from 1.0 to 0.1 mm wavelengths. Astrophysics, earth atmosphere research and solar system exploration can all benefit from the development of such sensor capabilities. Technology status evaluations are presented for Shottky-diode and SIS mixers, solid state and backward wave oscillators, intermodulation frequency amplifiers, and digital autocorrelator and acoustooptic spectrometers.
