Data Augmentation for Imbalanced HRRP Recognition Using Deep Convolutional Generative Adversarial Network

IEEE Access, 2020
In radar high-resolution range profile (HRRP) recognition, the recognition accuracy will decline when the training samples in some classes (majority classes) greatly outnumbers other classes (minority classes).
