Abstract

In order to correlate high resolution/precision interferometric POL-SAR images with the underlying ground truth, it is essential to develop the RCS matrix expressions for simple, canonical shapes in closed analytic form and to provide numerical algorithm verification analyses. This is achieved by extending the common geometrical optics (GO) and physical optics (PO) scalar RCS closed form solutions via the Geometrical Theory of Diffraction (GTD) of J.B. Keller and the Physical Theory of Diffraction (PTD) of P.Ya. Ufimtsev to the full polarimetric, slightly bistatic cases as required for proper implementation in modern wideband (multi spectral and impulse) POL-SAR systems calibration and image normalization procedures
