Abstract
The dissertation considers an inverse acoustic obstacle scattering
problem in which the incident field is generated by a point source and the
measurements are made in the near field region.
Three methods to solve the problem of reconstructing the support of
an unknown sound-soft or sound-hard scatterer from the near field
measurements are presented. Methods are modifications of Kirsch
factorization and modified Kirsch factorization methods. Numerical
examples are given to show the practicality of one of the methods.
