Applying Polarimetric Target Decomposition to 2D Turntable ISAR Imagery of a Complex Vehicle by Sevket Demirci

“…To characterize target’s anisotropic scattering properties, wide-angle case is considered through the employment of a distinct polarimetric analysis procedure based on angular averaging of the covariance matrix. The results of the application of the three types of coherent decomposition, that is, Pauli, Krogager, and Cameron decomposition, and one incoherent decomposition, that is, eigenvector/eigenvalue decomposition, are analyzed and compared in terms of the identification of the physical scattering mechanisms. …”

Using pattern classification to measure adaptation to the orientation of high order aberrations. by Lucie Sawides, Carlos Dorronsoro, Andrew M Haun, Eli Peli, Susana Marcos

“…Using the orientation of the best fitting ellipse of angularly averaged integrated PSF intensities (weighted by the subject's responses) we found that in 4 subjects the positive PSF response was close to the subject's natural PSF orientation (within 21 degrees on average) whereas the negative PSF response was almost perpendicularly oriented to the natural PSF (at 76 degrees on average).…”
