High‐Resolution Range Profile Sequence Recognition Based on Transformer with Temporal–Spatial Fusion and Label Smoothing

Advanced Intelligent Systems, Volume 5, Issue 11, November 2023., 2023
To further improve the performance of high‐resolution range profile sequence recognition, a transformer with temporal–spatial fusion and label smoothing is proposed, which can extract deep global features in both temporal and spatial domains and adopt the attention fusion mechanism to realize efficient feature fusion.

One‐dimensional convolutional neural networks for high‐resolution range profile recognition via adaptively feature recalibrating and automatically channel pruning

International Journal of Intelligent Systems, Volume 36, Issue 1, Page 332-361, January 2021., 2021
Abstract High‐resolution range profile (HRRP) has obtained intensive attention in radar target recognition and convolutional neural networks (CNNs) are among predominant approaches to deal with HRRP recognition problems. However, most CNNs are designed by the rule‐of‐thumb and suffer from much more computational complexity.
