A tutorial on synthetic aperture radar
Alberto Moreira,Pau Prats-Iraola,Marwan Younis,Gerhard Krieger,Irena Hajnsek,Konstantinos Papathanassiou +5 more
TL;DR: This paper provides first a tutorial about the SAR principles and theory, followed by an overview of established techniques like polarimetry, interferometry and differential interferometric as well as of emerging techniques (e.g., polarimetric SARinterferometry, tomography and holographic tomography).

T. Le Toan,Shaun Quegan,Malcolm Davidson,Heiko Balzter,Philippe Paillou,Konstantinos Papathanassiou,S. Plummer,Fabio Rocca,Sassan Saatchi,Herman H. Shugart,Lars M. H. Ulander +10 more
TL;DR: In this article, a P-band polarimetric SAR with interferometric capability is used to measure the magnitude and distribution of forest biomass globally to improve resource assessment, carbon accounting and carbon models, and to monitor and quantify changes in terrestrial forest biomass.
Journal ArticleDOI
Emission of rough surfaces calculated by the integral equation method with comparison to three-dimensional moment method simulations
TL;DR: The results based on the new version (advanced IEM) indicate that significant improvements for emissivity prediction may be obtained for a wide range of roughness scales, in particular in the intermediate roughness regions.
Journal ArticleDOI
Inversion of surface parameters from polarimetric SAR
TL;DR: It demonstrates how three polarimetric parameters, namely the scattering entropy, the scattering anisotropy, and the alpha angle may be used in order to decouple surface roughness from moisture content estimation offering the possibility of a straightforward inversion of these two surface parameters.
