MTFNet: A Lightweight Multi-Scale Time–Frequency Neural Network for Multi-Class Event Recognition in DAS-Based Perimeter Security

Distributed Acoustic Sensing (DAS) has emerged as a pivotal technology for perimeter security. However, existing DAS event recognition methods have inherent limitations. Single-domain modeling has limited feature representation, while conventional multi-domain fusion methods require converting one-dimensional signals i...
