Autofocus for inverse synthetic aperture radar (ISAR) imaging [PDF]
Signal Processing, 2001 Autofocus is a key step of inverse synthetic aperture radar (ISAR) imaging. In this paper four new approaches to autofocussing based on the application of beamforming and subspace concepts to ISAR imaging are developed. Their relations to maximum likelihood (ML) estimation are identified.

Performance limits for maritime Inverse Synthetic Aperture Radar (ISAR) [PDF]
, 2013 The performance of an Inverse Synthetic Aperture Radar (ISAR) system depends on a variety of factors, many which are interdependent in some manner. In this report we specifically examine ISAR as applied to maritime targets (e.g. ships). It is often difficult to get your arms around' the problem of ascertaining achievable performance limits, and yet ...

Terahertz inverse synthetic aperture radar (ISAR) imaging with a quantum cascade laser transmitter
Optics Express, 2010 A coherent transceiver using a THz quantum cascade (TQCL) laser as the transmitter and an optically pumped molecular laser as the local oscillator has been used, with a pair of Schottky diode mixers in the receiver and reference channels, to acquire high-resolution images of fully illuminated targets, including scale models and concealed objects.

Refocusing Moving Ship Targets in SAR Images Based on Fast Minimum Entropy Phase Compensation [PDF]
Sensors, 2019 Moving ship targets appear blurred and defocused in synthetic aperture radar (SAR) images due to the translation motion during the coherent processing. Motion compensation is required for refocusing moving ship targets in SAR scenes.

GLRT‐based detection of targets composed of distributed scattering centres
IET Radar, Sonar & NavigationAttributed scattering problems have been found to be helpful in inverse synthetic aperture radar (ISAR) imaging and target recognition problems. In this model, the scattering centres are divided into two categories: localised and distributed.
