Calibration of a polarimetric imaging SAR [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 1992
Calibration using point targets is discussed. The fourport network calibration technique is used to describe the radar error model. The processor ambiguity function and the radar distortion matrices are combined to form a generalized polarimetric ambiguity function.

Compact polarimetric SAR interferometry

open access: yesIET Radar, Sonar & Navigation, 2010
The authors discuss the role and performance of compact polarimetry in SAR interferometry. The considered SAR architecture transmits either a linearly polarised wave oriented at 45° or a circularly polarised one, and receives at horizontal and vertical polarisation.
