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 ...

HRRPGraphNet: Make HRRPs to be graphs for efficient target recognition
Electronics Letters, Volume 60, Issue 22, November 2024.Conventional techniques for High‐Resolution Range Profiles (HRRP) target recognition frequently encounter difficulties due limited data under non‐cooperated circumstances. We propose a novel use of graph‐theory of HRRPs and convert traditional sequence‐based recognition into a sophisticated graph classification task to achieve efficient target ...
