  In the paper, we experimentally study the inverse problem with the resonant
scattering determinant. We analyze the structure of characteristics of
perturbed linear waves. Assuming there is the common part of potential
perturbation propagating along the same strips, we estimate the common part of
the perturbed wave, and its Fourier transform.
  We deduce the partial inverse uniqueness from the Nevanlinna type of
representation theorem.
