Ray-model simulations of multipath interference of CW signals require precise computation of travel times along the paths between source and receiver. The travel times for each ray path must be known with sufficient precision to resolve the phase of the arrival. The effects of time-varying sound-speed profiles can then be simulated by allowing the state of the medium to change slightly for each multipath summation. This letter is concerned with a numerical method for making such computations.
