Stanford DAS-2 Array: Sand Hill Road Near-Surface Imaging Demo Dataset

An excerpt of recordings from the Stanford DAS-2 array along Sand Hill Road, acquired on Dec 23rd, 2022, using OptaSense ODH-3, is shared here. The data is used in the demo of the newly proposed "target" interferometry method with traffic-induced surface waves for near-surface characterization. The sampling rate is 250 samples per second. The repository for this new method can be found at https://github.com/syyuan93/vehicle_tracking_based_time_lapse_monitoring.
