| 摘要: |
| 基于深度学习的辐射源个体识别已经成为识别和认证无线设备的主要研究方法之一。然而，基于传统深度学习的辐射源个体识别算法不能直接应用于跨域（跨信道条件、跨接收机、跨接收时间等）辐射源个体识别场景，因为一个域上的数据训练的模型用于另一个域上进行推理，其效果通常会变差。调研了现有基于对比学习、迁移学习、域适应等先进深度学习的跨域辐射源个体识别方法，整理和归纳了跨域辐射源个体识别相关的开源数据集。分析了跨域辐射源个体识别存在的难题与挑战，展望了跨域辐射源个体识别发展趋势及未来研究方向，以助力深度学习在复杂电磁环境下辐射源个体识别的实用化。 |

| Abstract: |
| Specific emitter identification based on deep learning has become one of the main research methods to identify and authenticate wireless devices.However,the specific emitter identification algorithms based on traditional deep learning cannot be directly applied to cross-domain(cross-channel conditions,cross-receivers,cross-receiving time,etc.) emitter identification scenarios,because the model trained with data from one domain will generally be less effective when reasoning on data from another domain.The existing methods of cross-domain specific emitter identification based on deep learning including contrastive learning,transfer learning,and domain adaptation are investigated.The open-source data sets related to cross-domain specific emitter identification are also organized and summarized.The problems and challenges of cross-domain specific emitter identification are analyzed,and the development trend and future research directions of cross-domain specific emitter identification are prospected,in order to provide assistance for the practical application of deep learning in specific emitter identification in complex electromagnetic environments. |
