The properties of sonic boom propagation through turbulence continue to be explored by a ray theory approach. Ray theory is used to model the effects of refraction and subsequent folding of the wave front by an instantaneous realization of the turbulence. Comparison is made with other prediction methods. These results are compared with characteristics observed in sonic boom measurements. The relative contributions of the large and small scale modes of the turbulent field are evaluated.
