Abstract

The effects of Faraday rotation (FR) on longer wavelength (i.e. L or P-Band) spaceborne linearly full-polarized inferfermetry synthetic aperture radar (Pol-InSAR) processing are addressed. A model for linearly full-polarimetric InSAR data subject to Faraday rotation is investigated. Due to Faraday rotation, the received signal in each channel will be contaminated by backscattering signals from other polarimetric channels, which consequently reduce the coherence of the two single look complex SAR images received by the same channel for PolInSAR processing. The numerical simulation results are presented, which indicates that Faraday Rotation has significant impact on the coherence of the interferograms, especially for the spaceborne longer wavelength Pol-InSAR system.
