Remote sensing acquires and interprets small or large-scale data about the Earth from a distance. Using a wide range of spatial, spectral, temporal, and radiometric scales remote sensing is a large and diverse field for which this Handbook will be the key research reference. Illustrated throughout, an essential resource for the analysis of remotely sensed data, The SAGE Handbook of Remote Sensing provides researchers with a definitive statement of the core concepts and methodologies in the discipline.

Characterizing and monitoring the state of the Earth's vegetation cover for carbon and water cycle studies is of increasing importance in the face of evident global climate change. Radar remote sensing has long been recognized as a key component of an effective Earth observing system, due to the strong relationships of radar back scattering coefficient (sometimes also called radar backscatter) with vegetation geometric and compositional properties. Recognizing the sensitivity of radar measurements to vegetation variables, many radar instruments have been flown on airborne and spaceborne platforms for synoptic observations of vegetation cover. In particular, synthetic aperture ...
