Abstract

Accurately identifying specific types of active jamming is essential for optimizing radar resources and enhancing anti-jamming efficiency, particularly in the context of few-shot sample sizes, as discussed in this study. We first employ non-negative matrix factorization (NMF) to pre-process the radar signal. NMF enhances the feature representation of data while simultaneously augmenting the sample size. Subsequently, we propose a multi-dimensional fusion network (MDFN) designed to integrate high-dimensional features and classify jamming signals effectively. The proposed method demonstrates superior performance compared to existing approaches across twelve categories of jamming in few-shot scenario. Experimental results are presented to validate the reliability and effectiveness of the proposed method.
基于NMF与多维融合网络相结合的小弹干扰识别
正如本研究所讨论的,准确识别特定类型的有源干扰对于优化雷达资源和提高抗干扰效率至关重要,特别是在少量射击样本量的情况下。首先采用非负矩阵分解(NMF)对雷达信号进行预处理。NMF增强了数据的特征表示,同时增加了样本量。随后,我们提出了一种多维融合网络(MDFN),旨在整合高维特征并有效地对干扰信号进行分类。在少弹干扰情况下,与现有的12种干扰方法相比,该方法具有更好的性能。实验结果验证了该方法的可靠性和有效性。
