AB - <p style="text-align: justify;">A method for simulating acoustic wavefronts propagating under random
sound speed conditions is presented. The approach applies a level set method to solve
the Eikonal equation of high frequency acoustics for surfaces of constant phase, instead
of tracing rays. The Lagrangian nature often makes full-field ray solutions difficult to
reconstruct. The level set method captures multiple-valued solutions on a fixed grid.
It is straightforward to represent other sources of uncertainty in the input data using
this model, which has an advantage over Monte Carlo approaches in that it yields an
expression for the solution as a function of random variables.</p>
