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.
