Wide bandwidth, millimeter-resolution inverse synthetic aperture radar imaging [PDF]
Journal of the Optical Society of America A, 2017 The combination of wide bandwidth W-band inverse synthetic aperture radar imagery and high-fidelity numerical simulations has been used to identify distinguishing signatures from simple metallic and dielectric targets. Targets are located with millimeter-scale accuracy using super-resolution techniques.

Hybrid polarimetry inverse synthetic aperture radar
IET Radar, Sonar & NavigationThe inverse synthetic aperture radar (ISAR) system exploits the movement of the target to form its high‐resolution image. Further, the multi‐polarisation acquisition in ISAR collects additional information on the target's scattering properties and ...

An Autofocus Technique for High-Resolution Inverse Synthetic Aperture Radar Imagery [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2014 For inverse synthetic aperture radar imagery, the inherent sparsity of the scatterers in the range-Doppler domain has been exploited to achieve a high-resolution range profile or Doppler spectrum. Prior to applying the sparse recovery technique, preprocessing procedures are performed for the minimization of the translational-motion-induced Doppler ...

A near field spherical wave inverse synthetic aperture radar technique [PDF]
IEEE Antennas and Propagation Society International Symposium 1992 Digest, 1992 The authors present an imaging near-field spherical wave inverse synthetic aperture radar (SWISAR) algorithm based on a focusing operator of the scattered fields on the target surface. A spherical wave can be easily generated in an anechoic chamber using electrically small and low-cost horn antennas; no reflectors are used, avoiding surface tolerance ...

Compressive sensing for interferometric inverse synthetic aperture radar applications
IET Radar, Sonar & Navigation, 2016 The applicability of interferometric inverse synthetic aperture radar (InISAR) techniques to images reconstructed via compressive sensing (CS)‐based algorithms is investigated. Specifically, the three‐dimensional (3D) reconstruction algorithm is applied after exploiting CS for data compression and image reconstruction.
