Hybrid polarimetry inverse synthetic aperture radar

open access: yesIET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
The CTLR hybrid‐pol ISAR offers an efficient solution for non‐cooperative target applications, striking an optimal balance between conventional single‐pol ISAR and the widely used full‐pol ISAR. This approach is particularly advantageous for compact radar systems, such as those used in drones and small ground‐radar setups, where it could prove to be a ...

Random Stepped Frequency ISAR 2D Joint Imaging and Autofocusing by Using 2D-AFCIFSBL

open access: yesRemote Sensing
With the increasingly complex electromagnetic environment faced by radar, random stepped frequency (RSF) has garnered widespread attention owing to its remarkable Electronic Counter-Countermeasure (ECCM) characteristic, and it has been universally ...

Characterisation of Resident Space Objects and Synchronisation Error Compensation in Multistatic Interferometric Inverse Synthetic Aperture Radar Imaging

open access: yesIET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This article presents a study on interferometric inverse synthetic aperture radar (ISAR) for three‐dimensional imaging and rotational velocity estimation. The study focuses on synchronisation error compensation in a multistatic setup with three ground‐based radars and non‐orthogonal baselines.

Autofocus for inverse synthetic aperture radar (ISAR) imaging [PDF]

open access: yes
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.

Resolution and Micro-Doppler Effect in Bi-ISAR System (in English)

open access: yesLeida xuebao, 2013
Compared to the monostatic radar, bistatic radar has many special characteristics because of its spatial complexity. Bistatic Inverse Synthetic Aperture Radar (Bi-ISAR) can be employed as a radar imaging tool for obtaining non-cooperative target images ...

Statistical Analysis of Performance of Optimisation‐Based SAR Autofocus

open access: yesIET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
Transionospheric SAR autofocus is a variational algorithm designed to overcome the limitations of conventional autofocus methods in correcting ionospheric distortions in spaceborne SAR images. This study provides a systematic statistical analysis of its robustness, examining the effects of turbulence, clutter, and noise on performance.

Synthesis of Inverse Synthetic Aperture Radar (ISAR) Using Matlab

open access: yes, 2021
High-resolution radar images can be achieved by employing synthetic aperture radar (SAR) or inverse synthetic aperture radar (ISAR) techniques. It can be shown that SAR and ISAR have the same underlying theory but different configuration.
