New space-borne polarimetric SAR systems employ, or will employ, dual-pol imaging modes as well as full quad-pol imaging, e.g. PALSAR, RADARSAT-2, TERRASAR-X. Therefore questions arise as to the capabilities (and limitations) of these various dual-pol SAR imaging modes. One novel offshoot of our work on dual-pol SAR image analysis and polarimetric decompositions of dual-pol data was the idea to collect...
The accuracy with which distributed-target polarimetric calibration algorithms estimate crosstalk and the ratio of Tx-to-Rx channel imbalance is compared. The algorithms investigated are minor variants of previously-published algorithms but rederived for notational and definitional consistency. Numerical simulations were used to assess the algorithms' performance in the absence of noise. Results indicate...
In the past decade the use of fully polarimetric SAR (polSAR) systems has increased significantly due to their effectiveness in target classification and detection applications. While polSAR imagery has been extensively used to distinguish between different scattering mechanisms in a scene, there has been a lack of research in the exploitation of polarimetry to assist in image formation and in particular...
