摘要: Preliminary details of a 2-D synthetic aperture radiometer prototype operating from 50 to 55 GHz will be presented. The laboratory is being developed demonstrate the technologies and system design needed do millimeter-wave atmospheric soundings with high spatial resolution Geostationary orbit. concept deploy large thinned Y-array on geostationary satellite, use synthesis obtain images Earth without need for mechanically scanned antenna. consists 24 horn antennas, MMIC receivers, digital cross-correlation subsystem
