The Design Of The Esa Multiband Imaging Microwave Radiometer Mimr

The analysis of affections to the cold space calibration source of ChangE-1 payload Microwave Detector

“…First, the instrument uses switches for connecting to observation signals and calibration signals by turning in a cycle, such as (Njoku et al, 1980;Swanson and Riley, 1980), MSR (Microwave Scanning Radiometer) (Morita et al, 1989), ATSR/MWR (Along-Track Scanning Radiometer/Microwave Radiometer) (Bernard et al, 1993;Eymard et al, 1994) and TMR (TOPEX/Poseidon Microwave Radiometer) Ruf et al, 1995). Second, during the scan, the entire antenna assembly rotates as a unit, and the stationary hot-load and coldsky reflectors are viewed as the feeds pass beneath them, so the radiometer view hot/cold calibration target once per scan, such as SSM/I (the Defense Meteorological Satellite Program operational Special Sensor Microwave Imager) (Colton, 1999;Hollinger et al, 1990), MIMR (the Multifrequency Imaging Microwave Radiometer) (Menard and Reynolds, 1991;Thornbury, 1990) and AMSR (Advanced Microwave Scanning Radiometer). 1,2 Microwave Detector is designed as the second structure.…”
