Recent Advancements of Multi-modal Radar & SAR Imaging

Radar polarimetry radar interferometry and polarimetric SAR interferometry represent the current culmination in ´microwave remote sensing´ technology. Whereas with radar polarimetry, the textural fine-structure, target orientation, symmetries and material constituents can be recovered with considerable improvement above that of standard ´amplitude-only´ radar, by implementing ´radar interferometry´, the spatial (in depth) structure can be explored. With polarimetric interferometric synthetic aperture, radar (POL-IN-SAR) imaging it is possible to recover such co-registered textural and spatial information from POL-IN-SAR digital image data sets simultaneously, including the extraction of digital elevation maps (DEM) from either polarimetric (scattering matrix) or interferometric (dual antenna) SAR systems.
