Stability of the Solution to Inverse Obstacle Scattering Problem
It is proved that if the scattering amplitudes for two obstacles (from a large class of obstacles) differ a little, then the obstacles differ a little, and the rate of convergence is given. An analytical formula for calculating the characteristic function of the obstacle is obtained, given the scattering amplitude at a fixed frequency.
متن کاملThe stability of the solution of an inverse spectral problem with a singularity
This paper deals with the singular Sturm-Liouville expressions $ ell y = -y''+q(x)y=lambda y $ on a finite interval, where the potential function $q$ is real and has a singularity inside the interval. Using the asymptotic estimates of a spectral fundamental system of solutions of Sturm-Liouville equation, the asymptotic form of the solution of the equation (0.1) and the ...
متن کاملUniqueness of the Solution to Inverse Scattering Problem with Backscattering Data
Let q(x) be real-valued compactly supported sufficiently smooth function. It is proved that the scattering data A(−β, β, k) ∀β ∈ S, ∀k > 0, determine q uniquely. MSC: 35P25, 35R30, 81Q05;
متن کاملUniqueness of the solution to inverse scattering problem with non-overdetermined data
Let q(x) be a real-valued compactly supported sufficiently smooth function. It is proved that the scattering data A(−β, β, k) ∀β ∈ S, ∀k > 0, determine q uniquely. Under the same assumptions on q(x) it is proved that the scattering data A(β, α0, k) ∀β ∈ S, ∀k > 0, and a fixed α0, the direction of the incident plane wave, determine q uniquely. The above scattering data are non-overdetermined in ...
متن کاملUniqueness of the Solution to Inverse Obstacle Scattering Problem
It is proved that the scattering amplitude known at a fixed frequency, a fixed direction of the incident plane wave and all directions of the scattered wave in a solid angle, however small, determine uniquely the shape of a strictly convex obstacle with a smooth but not analytic boundary on which the Dirichlet boundary condition is assumed.
