• The invariant imbedding method combined with the time domain wave splitting technique is applied to the inverse problem for the telegraph equation ∂^2_tu= (1 / r)∇・(p∇u)-b∂_tu+qu in a stratified half-space. The zeroth, second and fourth moments of the 3-D fields are used to reduce the three-dimensional problem to a set of one-dimensional problems. The imbedding equations for R_0, R_2 and R_4, respectively the zeroth, second and fourth moments of the reflection operator, are derived. Numerical results for the reconstruction are presented using the reflection data on the surface.
