Imaging with Synthetic Aperture Radar
TLDR
In this article, the authors describe a field that has been transformed by the recent availability of data from a new generation of space and airborne systems and offer a synthetic geometrical approach to the description of synthetic aperture radar, one that addresses physicists, radar specialists, as well as experts in image processing.Abstract:

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).

Compressive Radar Imaging
TL;DR: It is demonstrated that CS has the potential to make two significant improvements to radar systems: eliminating the need for the pulse compression matched filter at the receiver, and reducing the required receiver analog-to-digital conversion bandwidth so that it need operate only at the radar reflectivity's potentially low "information rate" rather than at its potentially high Nyquist rate.

An above-ground biomass map of African savannahs and woodlands at 25 m resolution derived from ALOS PALSAR
Alexandre Bouvet,Stéphane Mermoz,Thuy Le Toan,Ludovic Villard,Renaud Mathieu,Laven Naidoo,Gregory P. Asner +6 more
TL;DR: In this paper, a map of the above-ground woody biomass (AGB) of African savannahs and woodlands at a resolution of 25 m is presented, based on the 2010 L-band PALSAR mosaic produced by JAXA.
Journal ArticleDOI
Sparse microwave imaging: Principles and applications
TL;DR: The sparse microwave imaging introduces the sparse signal processing theory to radar imaging to obtain new theory, new system and new methodology of microwave imaging to achieve benefits in several aspects, including improvement of image quality, reduction of data amount for sparse scene and enhancement of system performance.
Journal ArticleDOI
Volcanology: lessons learned from synthetic aperture radar imagery
TL;DR: In this article, the authors review the contributions of satellite SAR imagery to volcano science, monitoring, and hazard mitigation, and explore the future potential for SAR in volcanology, which can then be used to develop new models of how volcanoes work and to improve quantitative forecasts of volcanic activity as a means of mitigating risk from future eruptions.
