摘要:

复杂电磁环境中存在着大量的参数复杂多变的有源干扰,基于原始图卷积网络(graph convolutional networks, GCN)的干扰识别方法适应性较差,且无权图无法反映相邻节点聚合特征的权重。针对以上问题,提出一种基于雷达信号高阶特征的多尺度加权图卷积网络的雷达有源干扰识别方法。通过提取雷达回波信号时域、频域和时频域的特征构成高阶特征向量,采用图结构数据定义识别单元,用于表示识别单元的时间和空间信息,最后构建多尺度图卷积网络模型进行识别。试验结果表明,当回波信号的干信比大于3 dB时,所提方法对各类干扰的识别率可达90%以上,在干扰参数复杂多变场景下可保持稳健的识别性能。

Abstract:

In complex electromagnetic environments, numerous active jamming signals with highly variable parameters exist. Jamming recognition methods based on graph convolutional networks (GCN) exhibit poor adaptability, and unweighted graphs fail to reflect the weights of neighboring node aggregated features. To address these limitations, this paper proposes a radar active jamming recognition method using multi-scale weighted GCN based on radar signal high-order features. The method extracts features from the time domain, frequency domain, and time-frequency domain of radar echo signals to form high-order feature vectors. It defines recognition units using graph-structured data to represent temporal and spatial information. A multi-scale GCN model is subsequently constructed for recognition. Experimental results demonstrate that when the jammer-to-signal ratio exceeds 3 dB, the proposed method achieves over 90% recognition accuracy for various jamming types. It maintains robust recognition performance even in scenarios with complex parameter variations.
