Fully Polarimetric Radar Cross‐Section and High‐Resolution Range Profile Co‐Modulation via Diversely Time‐Modulated Metasurface

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
A diversely time‐modulated metasurface enables broadband co‐modulation of fully polarimetric radar cross section and high‐resolution range profiles. By integrating anti‐parallel PIN diodes and programmable temporal coding, the platform dynamically redistributes scattering among HH/VV and HV/VH channels, generating tunable target weakening, false ...

A Robust Algorithm for Simulation‐Measured Cross‐Domain Few‐Shot HRRP Target Recognition

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This paper proposes CROF‐Net, a robust cross‐domain few‐shot HRRP target recognition algorithm to address the challenges of scarce labeled measured samples and simulation‐measured domain shift. The method adopts low‐order statistical moment alignment, scattering peak‐aware feature extraction, and orthogonally regularized multi‐subcenter metric ...

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

3‐D Micro‐Motion Parameters Estimation of Smoothly Precession Cone‐Cylinder Targets Based on Monostatic Radar

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This article proposes a method that a single radar was used for the first time to estimate the micromotion parameters and geometric information of a precession cone‐cylinder target with unknown precession angle by utilising the relationship between the curves of each scattering point in high‐resolution range profile (HRRP) and time–frequency diagram ...

Velocity estimation and compensation approach for SFW radar visa IGSS

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This paper introduces a pioneering velocity estimation technique utilizing the fractional Fourier transform (FrFT) to address these limitations. Leveraging the characteristic of the Doppler signal from a moving target, which manifests as a chirp signal with a rate proportional to the target's velocity, the FrFT is utilized for precise velocity ...
