An ISAR target motion estimation algorithm based on a differential semblance criterion

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This study presents a novel approach for improving rotational motion estimation in multistatic Inverse Synthetic Aperture Radar (ISAR) imaging through a Differential Semblance Optimization (DSO) criterion. By reducing discrepancies across images from multiple transmitter–receiver pairs, our method enables precise yaw rotation estimation and produces ...

Joint Noise Suppression and Resolution Enhancement of ISAR Images Using Integrated Neural Networks

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This study proposes an integrated neural network for simultaneous noise suppression and resolution enhancement in inverse synthetic aperture radar (ISAR) images. The proposed approach sequentially combines separate generative models for each task and optimizes them using a joint learning strategy.

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 ...

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.
