A Novel Strategy for Radar Imaging Based on Compressive Sensing [PDF]

, 2010
Radar data have already proven to be compressible with no significant losses for most of the applications in which it is used. In the framework of information theory, the compressibility of a signal implies that it can be decomposed onto a reduced set of

Imaging of Complex Targets With Rotating Parts via WSF–SRDI

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This letter addresses the wideband ISAR imaging problem for targets with rotating components. A novel wideband subband fusion SRDI (WSF‐SRDI) framework is proposed to resolve RCM and nonlinear phase distortion. Both theoretical analysis and simulation results verify the effectiveness of the method under low SNR conditions, providing an efficient ...

Resolution Analysis of Microwave Radar Coincidence Imaging for Multiple Imaging Points

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
In this paper, we propose an Eigen Subspace Characterisation method for analysing the azimuth resolution of an MRCI system, particularly in scenarios involving multiple imaging points within a coherent area. The ESC method is implemented by first constructing the eigen subspace from the reference signal matrix of the MRCI system using the Singular ...

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 ...

Dynamic Multistatic Synthetic Aperture Radar Imaging: Resolving Motion via Differential Semblance and k‐Space Diversity

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
Moving targets often appear defocused and displaced in SAR imagery, complicating detection and recognition—especially when displaced into cluttered regions, where signal‐to‐background ratio is reduced. This work presents a multistatic SAR framework that extracts moving target signatures and reconstructs focused images, providing new insights into the ...

Development of a MIMO Radar System Demonstrator - Calibration and Demonstration of First Results [PDF]

, 2012
The success of current spaceborne Synthetic Aperture Radar (SAR) is boosting the performance requirements of next generation systems. In order to cope with the evolution of SAR the design of the new systems will need to meet higher requirements for ...

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 ...
