Abstract

Spaceborne microwave radiometer is nowadays one of the most important means in earth observation and space exploration. It plays an important role in the remote sensing application because of its all-day, all-weather observation capability for earth surface observation and atmospheric sounding. Calibration is the basis of quantitative application, and calibration precision is the integrated result of several instrument performances, such as sensitivity, stability and so on. As a result, it is important to analyze the effects of the concerned factors which affect the calibration precision. In this paper, Orthogonal Array Test Design Method is used to theoretically analyze how the transmission parameters of the calibration system contribute to the calibration uncertainties. Based on the result, some suggestion is proposed to the design of a spaceborne radiometer calibration system.
