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 ...

ISAR Imaging of Ship Targets Based on an Integrated Cubic Phase Bilinear Autocorrelation Function

Sensors, 2017
For inverse synthetic aperture radar (ISAR) imaging of a ship target moving with ocean waves, the image constructed with the standard range-Doppler (RD) technique is blurred and the range-instantaneous-Doppler (RID) technique has to be used to improve ...

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.

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.

Research of InISAR imaging based on joint translational compensation

The Journal of Engineering, 2019
In order to solve the problem that conventional inverse synthetic aperture radar three-dimensional (InISAR 3D) imaging methods need too much computation and so many restrictions in image registration step, this study proposes an InISAR 3D imaging ...

SDRnet: A Deep Fusion Network for ISAR Ship Target Recognition Based on Feature Separation and Weighted Decision

Remote Sensing
Existing methods for inverse synthetic aperture radar (ISAR) target recognition typically rely on a single high-resolution radar signal type, such as ISAR images or high-resolution range profiles (HRRPs).
