Wide bandwidth, millimeter-resolution inverse synthetic aperture radar imaging [PDF]

open access: greenJournal 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.

An Autofocus Technique for High-Resolution Inverse Synthetic Aperture Radar Imagery [PDF]

open access: yesIEEE 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 ...

Chip-based photonic radar for high-resolution imaging [PDF]

open access: yesarXiv, 2019
Radar is the only sensor that can realize target imaging at all time and all weather, which would be a key technical enabler for future intelligent society. Poor resolution and large size are two critical issues for radars to gain ground in civil applications.

Compressive sensing for interferometric inverse synthetic aperture radar applications

open access: yesIET 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.

A near field spherical wave inverse synthetic aperture radar technique [PDF]

open access: greenIEEE 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 ...
