摘要

通过对外部和内部校准参数的仔细分析以及对单个接收机前端的精确建模，开发了表征和减轻SMOS数据长期和短期漂移的有效方法。一种表征这种漂移的方法已经成功地开发出来，并用于减少测量的天线温度变化。

Stability of the MIRAS amplitude calibration

Efficient methods to characterize and mitigate long-and short- term drifts in SMOS data have been developed after careful analysis of the external and internal calibration parameters and by accurate modeling of the individual receiver front-ends. A method to characterize this drift has been successfully developed and used to reduce the measured antenna temperature variations.
