چکیده
We deal with the inverse scattering problem of determining the surface impedance of a partially coated obstacle. We prove a stability estimate of logarithmic type for the impedance term by the far field measurements.

The Determination of the Surface Impedance of a Partially Coated Obstacle from Far Field Data
A variational method is given for determining the essential supremum of the surface impedance of a partially coated perfect conductor from a knowledge of the far field pattern of the time-harmonic electric field at fixed frequency. It is assumed that the shape of the scatterer has been determined (e.g., by solving the far field equation and using the linear sampling method). Numerical examples ...
متن کاملHow to make the reconstruction of obstacles more (or less) accurate from exterior measurements
In this paper, we deal with the acoustic inverse scattering problem for detecting obstacles from the far field data. The complex obstacle is characterized by its shape, its type of boundary conditions and the boundary coefficients (surface impedance). We particularly show how one can use the boundary coefficient, distributed on the surface of the obstacle, to design obstacles which can be recon...
متن کاملObstacle and Boundary Determination from Scattering Data
In this paper, we are concerned with the identification of complex obstacles from the scattering data for the acoustic problem. The complex obstacle is characterized by its shape and the boundary values of the impedance coefficient. We establish pointwise formulas which can be used to reconstruct the shape of the obstacle and give explicitly the values of the surface impedance as a function of ...

متن کاملOn Detection and Visibility of a Complex Obstacle Using Multipoles Sources from Far Field Data
We deal with the acoustic inverse scattering problem for detecting an obstacle with mixed boundary conditions from the far field map. We show how the geometric properties and the material parameter distributed on the surface are involved in the obstacle reconstruction numerically. The main advance of this research on our recently work (SIAM J. Applied Math, 67(4), 2007) is the higher-order asym...
