Development of High Temperature Noise Source (HTS) for Advanced Microwave Scanning Radiometer 2 (AMSR2)

The Advanced Microwave Scanning Radiometer 2 (AMSR2) was developed and provided to Global Change Observation Mission satellite (GCOM-W1) led by Japan Aerospace Exploration Agency (JAXA). AMSR2 observes the global water and energy cycling, such as water vapor, precipitation, sea surface temperature, soil moisture, etc. AMSR2 mounted on GCOM-W1 will be launched by H-IIA Rocket in winter period of FY2011. AMSR2 is now under the spacecraft protoflight test. This paper describes the development and evaluation result of High Temperature Noise Source (HTS), a calibration warm load of AMSR2.
