Deinterleaving of Intercepted Radar Pulse Streams via Temporal Convolutional Attention Network

In the domain of electronic warfare, radar signal deinterleaving emerges as the foundational and indispensable phase of electronic reconnaissance. The ever-increasing complexity of electromagnetic environments, further compounded by technological advancements, such as multifunction radars (MFRs), has led to the inadequacy of traditional deinterleaving techniques. To tackle these challenges, this article introduces the temporal convolutional attention network (TCAN) framework. This framework harmoniously combines a TCN with an advanced attention mechanism, thereby significantly enhancing the system's signal sorting proficiency. Through rigorous experimental validation, we demonstrate that TCAN consistently outperforms existing baseline methods. This superiority is particularly pronounced under conditions of signal sparsity and in nonideal environments, which are typified by pulse loss, spurious pulses, and measurement errors. Furthermore, we conduct a thorough analysis to elucidate the profound impact of various input formats and multiparameter features on deinterleaving performance. By meticulously examining these factors, we establish TCAN as a robust and versatile solution capable of effectively navigating the heightened complexity of modern radar signal environments. Our findings highlight TCAN's potential as a potent instrument for augmenting electronic reconnaissance capabilities amidst evolving electromagnetic challenges.
