摘要

法拉第旋转是l波段空间遥感中需要考虑的一个问题。对于像SMAP这样专注于土壤湿度的锥形扫描仪来说尤其如此，因为旋转角度随着扫描周围的位置而变化，而且在陆地上检索的角度是有噪声的。举例说明。这是确定旋转角度检索精度和处理陆地上法拉第旋转的最佳方法的研究的一部分。

Faraday rotation and the SMAP radiometer

Faraday rotation is an issue to be taken into account in remote sensing from space at L-band. This is especially so for a conical scanner such as SMAP with a focus on soil moisture because the rotation angle varies with position around the scan and because the angle retrieved over land is noisy. Examples are reported. This is part of research to determine the accuracy of the retrieval of the rotation angle and the optimum way to deal with Faraday rotation over land.
