DANTE: Physics-Informed Neural Operator for DAS-to-Velocity Waveform Reconstruction Without Co-located Seismometers
A physics-informed Fourier Neural Operator reconstructs particle velocity from DAS strain-rate measurements by enforcing kinematic and elastic-wave-equation constraints, yielding 15.3 dB mean SNR on synthetic tests and low kinematic residuals on real Utah FORGE data without fine-tuning.
