The deterioration in the performances of the infrared thin-film interference filters at low-temperature is crucial to the spaceborne remote sensing instruments.

With the increasingly extensive and in-depth application of quantitative Synthetic Aperture Radar (SAR) images, SAR calibration became a necessary technique in modern spaceborne SAR remote sensing.

Spaceborne microwave imaging instrument is an important about acquiring information in technology of satellite remote sensing. Its properties affect directly the satellite system.
