Due to the electron density and the geomagnetic field within the ionosphere, full polarization space-borne SAR systems at L-band or lower frequencies, such as the Phased Array type L-band Synthetic Aperture Radar (PALSAR), will suffer the effect of Faraday rotation. The corresponding compensation therefore should be considered. In this paper, by using a series of the PALSAR data sets in different Chinese regions, compensation based on the scattering matrix shows better results than that from the Alaska Satellite Facility.
