摘　　要：受辐射源硬件失真和接收机硬件失真的耦合作用,实际接收信号中带有当前辐射源系统和接收系统共同的“个体信息”,导致辐射源指纹识别技术(RFF)在跨接收系统场景下无法通用。为消除接收机染色效应,该文将接收机影响作为单独作用域,提出一种基于接收域分离的跨接收系统通用性辐射源指纹识别方法。该方法通过双标签多通道特征联合和域分离对抗重构方式实现信号中辐射源指纹作用域与接收机染色作用域分离,利用多部接收机数据预先训练网络对两种作用域的分离能力,聚焦辐射源指纹信息提取,从而提升辐射源指纹识别技术在跨平台跨接收系统、更新接收设备等场景下的适应能力。相比于直接特征提取和多接收机打包训练方式,所提方法能够真正适应实际无监督场景,且参与训练的源域接收机数目越多,域适应效果越好,不需要重复训练即可直接推广应用于新接收系统,具有较高的实际应用价值。Due to the coupling effect of emitter distortion and receiver distortion,the actual received signal contains the information of the current emitter system and the receiving system,which makes the Radio Frequency Fingerprinting(RFF)technology unable to be generalized in cross-receiving system scenarios.In order to eliminate the effect of receiver,in this paper,a universal RFF method across receiving systems based on receiving domain separation is proposed which considers the influence of the receiver as a separate scope.Through the dual-label multi-channel fusion feature and domain separation adversarial reconstruction method,after trained with multi-receiver data in the source domain,the proposed method can separate domains of transmitting and receiving,extract emitter fingerprint information,which improves the generalization of RFF in scenarios such as cross-receiving system and cross-platform.Compared with the existing cross-receiver RFF methods,the proposed method can truly adapt to the actual unsupervised scenario.And the more the number of source domain receivers participating in the training,the better the domain adaptation effect.It can be directly applied to the new receiving system without repeated training,which has high practical application value.
