Abstract :
The solution of three dimensional inverse scattering problem using first-order Born and Rytov approximations are implemented for the reconstruction of an unknown dielectric sphere. Synthetic scattered field data from a sphere are generated using the Mie scattering method. The results show that the Rytov approximation provides better estimation of the sphere´s parameters in comparison with the Born approximation.
