On the near field measurement for the inverse scattering problem for ocean acoustics
نویسندگان
چکیده
Recently a near field measurement approach has been proposed to deal with inverse ocean acoustics. It uses the near field of the scattered wave instead of the far field pattern. In this paper we justify how this near field of the scattered wave can be determined by the given Green’s function on some surface surrounding the object to detect. This justifies the usual measurements in ocean acoustics. We also discuss the eigenvalue assumption, which is one of the main obstacles of the inverse problem in a slab.

Inverse scattering problem for the Impulsive Schrodinger equation with a polynomial spectral dependence in the potential
In the present work, under some di¤erentiability conditions on the potential functions , we rst reduce the inverse scattering problem (ISP) for the polynomial pencil of the Scroedinger equation to the corresponding ISP for the generalized matrix Scrödinger equation . Then ISP will be solved in analogy of the Marchenko method. We aim to establish an e¤ective algorithm for uniquely reconstructin...
متن کاملDirect and Inverse Medium Scattering in a 3d Homogeneous Planar Waveguide
Time-harmonic acoustic waves in an ocean of finite height are modeled by the Helmholtz equation inside a layer with suitable boundary conditions. Scattering in this geometry features phenomena unknown in free space: resonances might occur at special frequencies and wave fields consist of partly evanescent modes. Inverse scattering in waveguides hence needs to cope with energy loss and limited a...
متن کاملAn Analytical Solution for Inverse Determination of Residual Stress Field
An analytical solution is presented that reconstructs residual stress field from limited and incomplete data. The inverse problem of reconstructing residual stresses is solved using an appropriate form of the airy stress function. This function is chosen to satisfy the stress equilibrium equations together with the boundary conditions for a domain within a convex polygon. The analytical solu...

We also aim at developing a method for probing the ocean and ocean sediment at larger depth for imaging submerged objects at high resolution. We aim to use nonlinear scattering of sound in the presence of inhomogeneities to obtain high resolution images at high penetration depth. Through the developed theory, we can tackle the problem of high attenuation of acoustic field at high frequencies in...
متن کامل15: Investigation of Statistical Inference Methodologies Through Scale Model Propagation Experiments
In the ocean acoustics community over the past two decades, statistical inference of ocean waveguide properties1–5 has effectively replaced matched-field and inversion type approaches. 6 This change in perspective is based on the realization that the multi-parameter inverse problem for ocean waveguides is non-unique, resulting in many possible good solutions and no consistent way to discriminat...
