xdas.synthetics.randn_wavefronts()[source]#

Generate a large random-noise synthetic DAS DataArray.

Returns a 200 s × 100 km array (10 Hz temporal, 100 m spatial sampling) with step-onset noise bursts simulating P- and S-wave arrivals from a single source located 20 km off-axis.

Returns:

Synthetic DAS data with time and distance coordinates.

Return type:

DataArray
