DEMON Analysis: Reading a Vessel’s Propulsion from Its Own Noise
A working note on a classical technique that still earns its place alongside deep learning — and one way it caught a bug that spectrograms missed.

A Physics-Grounded Synthetic Underwater Acoustic Dataset for Underwater Domain Awareness
Full-factorial waveform generation from first-principle acoustic models — 12,000 physics-grounded clips across four vessel classes and ambient ocean noise, with corrected ambient-noise modelling, physics-based cavitation, and worked verification calculations. Openly released for self-supervised pretraining.
