Multifrequency Spaceborne Synthetic Aperture Radar Data for Backscatter-Based Characterization of Land Use and Land Cover

چکیده
Polarimetric synthetic aperture radar remote sensing extracts the information about target using decomposition models to separate polarimetric into single-bounce (contributed by smooth surfaces), double-bounce urban structure), and volume (mainly due vegetation cover) scattering components. The penetration capacity of electromagnetic wave surface increases with decrease in its frequency. This study explores compares for scattering-based characterization land use cover multifrequency spaceborne sensor datasets that were acquired over San Francisco, CA, USA. present work parameters coherent (Pauli), roll-invariant (Barnes), eigenvalue–eigenvector (Cloude), compact-polarimetric (Raney) modeling approaches structures, waterbody, cover. use/cover classification was performed based on response scatterers a support vector machine classifier. outputs approach multisensor, multifrequency, multi-polarization data have shown reasonable accuracy classifying fail characterize oriented structures cause misclassification as vegetation. higher-order could improve interpretation different targets classification.

Land Cover Classification Using NASA/JPL Polarimeric Synthetic Aperture Radar (POLSAR) Data
This study intends to investigate the use of NASA/JPL POLSAR data (multilook Cand L-bands) for classifying land cover features, such as vegetation (i.e. grass, rice paddy, rubber), natural feature (i.e. river), and man-made features (i.e. canal, highway, runway, built-up area). Covering the area of Jitra, the 10 meters resolution air-borne POLSAR data acquired on 3 December 1996 was used in thi...
