It is difficult to detect and measure slow moving natural objects from a space-borne SAR observation. This paper presents a simple and efficient method to retrieve moving velocity from quad-pol SAR data acquired by dual receive antenna (DRA). The core idea is to exploit the slight observation time difference between different polarizations (H- and V-pol transmitted signals). The difference of scattering...
Korea Aerospace Research Institute (KARI) has prepared the Fifth Korea Multi-Purpose SATellite (KOMPSAT-5) which is a high resolution X-band (9.66 GHz) Synthetic Aperture Radar (SAR) satellite. The KOMPSAT-5 will provide three kinds of imaging mode, Standard mode (ST-mode, 3 m, and 30 km swath), High resolution mode (HR-mode, 1 m, and 5 km swath), and Wide swath mode (WS-mode, 20 m, and 100 km swath)...
In this study we analyze Radarsat-2 quadruple polarization (quad-pol) mode data acquired over the Everglades wetlands in south Florida. We analyzed the phase information of each polarization mode independently, and obtained similar fringe patterns representing water level changes in all four interferograms. It is surprising, because common scattering theories indicate that cross-polarization (cross-pol)...
