Abstract
A perturbation method has been developed for determining small variations in sound speed from normal‐incidence measurements of the plane‐wave reflection coefficient as a function of frequency [J. K. Cohen and N. Bleistein, SIAM J. Appl. Math. 32, 784–799 (1977)]. We propose an analogous method for determining the compressional wave attenuation profile of an ocean bottom with known velocity profile from measurements of the reflection coefficient as a function of incident angle at a fixed frequency. The technique utilizes the fact that the attenuation can be treated as a small imaginary perturbation in the total wavenumber. Results are presented for a simple example. [Work supported by NORDA.]
