Paper Title:
The Study on Calibration Target with Temperature Adjusted Function for 10GHz~90GHz Microwave Radiometer
  Abstract

FY-3 meteorological satellite is the new generation of China’s polar-orbit meteorological satellite and be hoped to meet the operational weather prediction requirements of china and the global change research. The microwave imaging sounder (MWIS) and the microwave temperature sounder (MWTS) are two of its main payloads. To calibrate the linearity, sensitivity and stability of MWIS and MWTS accurately, the calibration target with temperature adjusted function is studied by Beijing Institute of Radio Metrology & Measurement (BIRMM). The configuration, technical specifi-cations and operational theory of the calibration target is presented in this paper. Because the two PID (Proportional-Integral-Differential) outputs by associating the parameter of liquid nitrogen cooling combined with electric heater is used, the target can provide a temperature adjusted brightness temperature output from 85K to 340K in 10GHz~90GHz to meet calibration requirements in lab environments.
