Abstract

Abstract:

In order to solve the poor generalization ability and low recognition accuracy problems of traditional synthetic aperture radar (SAR) target recognition methods in few-shot condition, a novel few-shot SAR target recognition method based on gated multi-scale matching network is proposed, which introduces weight gated unit and multi-scale feature extraction module into matching network. In the proposed method, the multi-scale feature extraction module is used to extract multi-scale features of different convolutional layers in matching network and the weight gated unit is used to weight different multi-scale features according to different recognition tasks. The proposed method achieves the effect of carrying out different recognition tasks mainly based on features of different layers thanks to the weight gated unit. The proposed method is evaluated on the moving and stationary target acquisition and recognition (MSTAR) dataset and achieved promising performance compared with state-of-the-art few-shot learning methods and few-shot SAR target methods. Furthermore, the proposed method shows good robustness in noisy environments.

Key words: synthetic aperture radar(SAR), radar target recognition, few-shot learning, fusion target recognition, metric learning, meta-learning
