Abstract

The Born and Rytov approximations are well-known for the important roles they play in describing acoustic wave propagation for both the direct and inverse scattering problems. However, considerable dispute still exists as to their relative merits and validity domains. The approximations are re-examined here, and several results are demonstrated without recourse to extensive numerical computations of possibly limited generality.
