法拉第旋转将是L波段星载极化SAR的一个问题。描述了校准受法拉第旋转影响的数据的两种方法。这两种方法都涉及雷达系统的串扰。第一种是基于Quegan方法，第二种是利用建筑区域的后向散射特性，其偏振方向角偏移与建筑物或房屋的墙壁的旋转角度有关。
Faraday rotation will be an issue of L-band spaceborne polarimetic SAR. Two approaches to calibrate data affected by Faraday rotation are described. In both approaches the cross-talk of radar system is involved. The first one is based on the Quegan method, and the second one is to use backscattering property of build-up areas, whose polarization orientation angle shift is related to the rotation angle of the wall of a building or a house.
