Other AbstractMicrowave spaceborne radiometer adopts sqare-law detection , so t he radiation of t he object received is linear to the outp ut voltage of the radiometer .Therefore ,the calibration of microwave spaceborne radiometer is performed by measuring the radiometer response to hot and cold references during operation.The hot reference is usually a blackbody under environmental temperat ure ,and the cold reference is Cosmic Background Radiation. According to Rayleigh-Jeans law ,the emission of the object is directly linear to it s absolute temperat ure.As the frequency of object increases , Rayleigh-J eans Law deviates f rom Planck's Blackbody Radiation Law ,and the radiation of object received should be calculated according to Planck's Blackbody Radiation Law.The calibration equations of millimeter and submillimeter radiometer are derived from he Planck's Law ,and t he formulas of the calibration references radiation are presented in millimeter and submillimeter bands.
