Study on the Calibration of the Millimeter and Submillimeter Wave Radiometer
星载毫米波亚毫米波辐射计定标的初步研究

Microwave spaceborne radiometer adopts sqare-law detection,so the radiation of the object received is linear to the output 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 temperature,and the cold reference is Cosmic Background Radiation.According to Rayleigh-Jeans law,the emission of the object is directly linear to ...
