A Method for Extracting and Imaging Weak Second‐Harmonic Signals in Harmonic Radar
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.Harmonic radar, as an emerging sensing technology, enables high‐sensitivity target detection and localization in complex environments by exploiting the nonlinear scattering characteristics of targets, such as the harmonic responses of electronic devices. Compared with conventional radar systems, it offers strong clutter suppression because most natural

An Improved Backprojection Autofocus Method for Synthetic Aperture Sonar
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.We propose an improved backprojection (BP) autofocus method for synthetic aperture sonar (SAS), which reduces the computational overhead of existing methods using Anderson acceleration (AA) and the sparsity of high‐intensity pixels in imagery. ABSTRACT Autofocus methods effectively compensate for multi‐source phase errors in synthetic aperture radar ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper presents a multistatic, frequency‐ and polarimetry‐adaptive autofocus algorithm (F‐Pol) for SAR imaging of moving targets undergoing complex, six‐degrees‐of‐freedom (6‐DoF) motion. Building on Localised Threshold Sharpness (LTS), the method exploits agreement across frequency sub‐bands and polarisation channels to improve pulse‐by‐pulse ...

Polarisation variation of linear polarised Bi‐ISAR system in space targets imaging
IET Radar, Sonar & Navigation, 2021 A bistatic inverse synthetic aperture radar (Bi‐ISAR) system is used to observe space targets through different viewing angles via a bistatic radar configuration. It is seen that the receiver of a linear polarised Bi‐ISAR system with a long baseline will

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 ...
