Sparse Array Configuration Optimization Based on Target Priors in Distributed ISAR Imaging

Electronics Letters, Volume 61, Issue 1, January/December 2025.
In this letter, we consider the sparse array configuration optimization problem for distributed inverse synthetic aperture radar (ISAR) imaging of long‐range targets, aiming to suppress the strong grating lobes caused by sparse sampling. Particularly, we propose a distributed ISAR configuration optimization method, which constructs an equivalent ...

Hybrid polarimetry inverse synthetic aperture radar

IET 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 ...

Efficient range alignment algorithm for real-time range-Doppler algorithm [PDF]

, 2017
When deriving a range-Doppler image or a time-frequency image of a fast-maneuvering target at long range, existing range alignment methods yield poor results due to the large numbers of range profiles (RPs) and range bins that are required for this task.

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

IET 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.

Statistical Analysis of Performance of Optimisation‐Based SAR Autofocus

IET 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.
