Journal ArticleDOI
Synthetic-aperture radar processing using fast factorized back-projection
TL;DR: It is shown that the back-projection integral can be recursively partitioned and an effective algorithm constructed based on aperture factorization is constructed and the number of operations is drastically reduced and can be made to approach that of fast transform algorithms.
Journal ArticleDOI

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
C-band repeat-pass interferometric SAR observations of the forest
TL;DR: The authors have developed a model to relate basic forest properties to INSAR observations and show that the coherence and interferometric effective height of a forested area change between image pairs.
Journal ArticleDOI
Repeat-pass SAR interferometry over forested terrain
TL;DR: In this paper, the authors derived a general system model including both radar system and scene scattering properties, which is used to interpret measurements over a forested area where the scene coherence varies between 0.2 and 0.5.
Journal ArticleDOI
Radiometric slope correction of synthetic-aperture radar images
TL;DR: An algorithm is described to obtain the slope correction from a SAR interferogram, which also enables retrieval of the full scattering geometry, and demonstrates that the spatial resolution and calibration error are adequate for most applications.
