摘要: 针对闭集场景中训练的辐射源个体识别模型部署在包含有新类别的辐射源个体环境条件中时会出现已知类识别性能下降以及新类识别错误的问题,提出了一种噪声变化场景下的基于开集域适应辐射源个体识别方法。利用最大最小阈值判别已知类和未知类并通过渐进式自训练的方法训练一个目标分类器用于测试场景。目标分类器的一个未知分类要同时拟合多个未知类的特征分布,可能会导致学习到的已知未知特征分布的边界混淆。基于此,提出了一个多中心损失用于增加目标已知类和未知类内的紧凑性以及类间的可区分性,可提高目标分类器判别的准确性。同时,为了减少源域和目标域之间因为噪声造成的指纹特征偏移问题,使用了基于原型到原型的对比学习来学习域不变特征。在公开数据集上进行了6组实验,所提方法在其中5组中的HOS指标好于其他方法,甚至在10dB-8dB的任务中HOS达到了93.8%,实验结果验证了所提方法的有效性。
