Adjoint modeling efficiently aids acoustic inversion by calculating steepest descent directions. This method reduces computational cost compared to using only forward models for underwater sound speed profile estimation.

Area of Science:

  • Oceanography
  • Acoustics
  • Geophysics

Background:

  • Adjoint modeling is a powerful technique for various inversion problems.
  • Its application in underwater acoustics remains underexplored.

Purpose of the Study:

  • To investigate the utility of adjoint modeling for acoustic inversion.
  • To apply adjoint methods to estimate sound speed profiles in underwater environments.

Main Methods:

  • Derived an adjoint model from a linearized forward acoustic propagation model.
  • Utilized the adjoint of a parabolic equation model for inversions.
  • Performed simulations for range-independent and range-dependent sound speed profiles.

Main Results:

  • Demonstrated successful acoustic inversions using adjoint methods.
