| Abstract: | This paper describes a ground calibration system(GCS) for measuring performance of spacebore microwave radiometers(SMR).This calibration system consists of radiation source calibrators,a rotating drum,a screen room and so on.The calibration data are sampled,processed and displayed in real time by a HP VL2/486 microcomputer,which also controls the velocity of the rotating drum and some SMR's parameters(integrating time,IF amplifier gain etc.).By groud calibration experiment,SMR calibration characteristics (calibration accuracy,nonlinear,nonstablity and sensitivity) are obtained. |
