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 ...

Open‐Set Recognition of Radar One‐Dimensional Range Profiles Based on Attention Mechanism and Multi‐Task Joint Training

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
To address the issues in radar automatic target recognition (RATR) based on high‐resolution range profiles (HRRP)—specifically, the inability of closed‐set methods to handle unknown categories and the limitation of conventional open‐set methods that can only reject unknown categories without further subdivision—this paper proposes the MHA–CoST open‐set

A Space‐Time‐Frequency Adaptive Processing Method for Dual‐Band Airborne Radar in Complex Electromagnetic Environments

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
In this paper, we first establish the dual‐band airborne radar wideband echo signal model and propose a space‐time‐frequency adaptive processing method based on it. Firstly, in the passive mode, the poles of the dual band are estimated by the matrix pencil method, and the incoherent components are estimated through the phase relationship between the ...

Cross‐Range Scaling for Spaceborne Radar Image of Space Target via Novel Method of Rotational Motion Estimation With Analytical Solution

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
In this article, a novel rotational motion estimation method via analytical solution is proposed and has been successfully applied to the cross‐range scaling. The proposed method can achieve high estimation accuracy without relying on iterative search procedures, which typically occur in existing methods and often result in high computational cost or ...

Performance Analysis on ISAR Imaging of Space Targets

Leida xuebao, 2017
Usually, in traditional Inverse Synthetic Aperture Radar (ISAR) systems design and mode selection for space satellite targets, coherent integration gain in azimuth direction hardly can be analyzed, which depends on target’s motion.

Characterisation and Classification of Resident Space Objects Using Radar Networks

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper describes a simulated environment for generating Inverse Synthetic Aperture Radar (ISAR) images and interferometric point clouds using a three‐receiver radar configuration, along with the creation of extensive datasets to train and evaluate deep learning models under varying Signal‐to‐Noise Ratio (SNR) conditions. Findings show that modified
