چکیده
Radar Polarimetry and Polarimetric SAR Interferometry represent the current culmination in ‘Microwave Remote Sensing’ technology based on the Antennas, Propagation, Radar and Systems. The purpose and procedure of polarimetry and polarimetric interferometry are shown in Fig. 1. With polarimetric radar sensing, it is possible to carry out 1) detection of targets, 2) decomposition of scattering mechanism, 3) classification of image, much more effectively compared to those of the single polarization radar. By implementing ‘radar interferometry’ the spatial (in depth) structure can be explored. With POLInSAR imaging, we can extract tree height for example, which is useful for biomass estimation, or we can monitor the disaster area suffered from earthquake or volcano eruption very precisely. The fundamental data is scattering matrix for polarimetric radar remote sensing. In this presentation, some observation results by Polarimetric Synthetic Aperture Radar (POLSAR) and Polarimetric and Interferometric Synthetic Aperture Radar (POLInSAR) are presented.

متن کاملAn Icon-Based Synoptic Visualization of Fully Polarimetric Radar Data
The visualization of fully polarimetric radar data is hindered by traditional remote sensing methodologies for displaying data due to the large number of parameters per pixel in such data, and the non-scalar nature of variables such as phase difference. In this paper, a new method is described that uses icons instead of image pixels to represent the image data so that polarimetric properties an...
