摘要
Synthetic aperture radar (SAR) is a powerful tool in remote sensing. Unlike optical image devices, SAR can observe target regions regardless of weather conditions, such as clouds, fog, and darkness. In this article, we con-sider the SAR target classification problems when avail-able SAR images having target labels are limited. To improve the classification performance, we propose a learning technique combining data augmentation using generative adversarial network (GAN) models and wave-let transformation. We conduct experiments to investigate the improvement of the proposed learning technique with the SAR images from the moving and stationary target acquisition and recognition data. From our experiment results, the proposed learning technique combining GAN-based data augmentation and wavelet transformation has shown greater improvement in SAR image classification when the available learning data is scarce
