Descripción del proyecto This project proposes a new architecture of sub-terahertz (THz) radiometers, which, for the first time, allows to combine high frequency selectivity, high sensitivity and high compactness, intended to be used in Earth-observation environmental sensing applications. There exists two radiometer detector types: 1) direct-detectors have best-possible sensitivity, but poor frequency selectivity, even when equipped with superconductive filters which require bulky and energy-demanding cryogenic cooling systems; 2) heterodyne-receivers, which are compact and have excellent frequency selectivity, but have inherently inferior signal-to-noise ratio. The PI, in his ERC CoG, has developed a new terahertz technology enabled by silicon micromachining, and has demonstrated world-record breaking narrow-band filters at sub-THz frequencies (Q=800 at 450 GHz, 1600 at 150 GHz), which, even at room temperature, are superior in performance to state-of-the-art THz filters requiring cryogenic cooling. Furthermore, he has developed a micromachined waveguide switch technology with unprecedented on/off ratio (insertion loss of 0.6 dB, isolation of 50 dB at 220 GHz). These results will be combined for the first time to a new direct-detector based radiometer architecture, enabled by a proposed micromachined switched-filter bank. Such a compact and high-performance radiometer can even be utilized in CubeSat high-density weather-satellite constellations, which are predicted to replace current weather satellites and enable a weather update every 15 minutes as opposed to several hours, which is required for dynamic monitoring for instance the development of severe storms. A proof-of-concept demonstrator for measuring the 183 GHz water line, capable of resolving sub-spectral lines at highest-possible sensitivity, will be implemented and tested in academic and space-industry environment, and appropriate innovation management and exploitation measures are taken in the project.
