Abstract

Distributed acoustic sensors (DASs) based on optical fibers have been claimed as one of the key enabling technologies for real-time spatiotemporal monitoring of car traffic, a crucial aspect of smart city implementation. With the technological issues of the physical layout elegantly solved using coherent processing, the signal processing of a large amount of generated data became a challenge. Autoencoders are machine learning tools that have shown their capability to identify anomalies in complex systems. In this project, we propose to use an autoencoder to detect anomalies in data collected in a field-installed DAS system.
