SAR-SIFT for Matching Multiple SAR Images and Radargrammetry [PDF]
PFG – Journal of Photogrammetry, Remote Sensing and Geoinformation Science, 2017 This article presents a new application of the SAR-SIFT algorithm proposed by Dellinger et al. (IEEE Trans Geosci Remote Sens 53:453–466, 2015) for the automatic generation of tie points (TPs). In particular, SAR-SIFT is applied on stereo-SAR images to extract corresponding points and determine their 3D position.

Experimental Synthetic Aperture Radar with Dynamic Metasurfaces
, 2017 We investigate the use of a dynamic metasurface as the transmitting antenna for a synthetic aperture radar (SAR) imaging system. The dynamic metasurface consists of a one-dimensional microstrip waveguide with complementary electric resonator (cELC ...

Joint sparsity-driven inversion and model error correction for radar imaging [PDF]
, 2009 Solution of inverse problems in imaging requires the use of a mathematical model of the observation process. However such models often involve errors and uncertainties themselves. The application of interest in this paper is synthetic aperture radar (SAR)
