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 ...

Adaptive soft threshold transformer for radar high‐resolution range profile target recognition
IET Radar, Sonar &Navigation, Volume 18, Issue 8, Page 1260-1273, August 2024.Aiming to target areas localisation and background noise, a framework termed Adaptive Soft Threshold Transformer (ASTT) is proposed for radar HRRP target recognition, which comprises a PE layer, ASTT blocks, and DWPM layers. Experiments based on a simulated dataset and a measured dataset show that the proposed ASTT has excellent target recognition ...
