Abstract:	The inverse scattering of buried inhomogeneous uniaxial dielectriccylinders is investigated. Dielectric cylinders of unknownpermittivities are buried in one half space and scatter a group ofunrelated waves incident from another half space where the scatteredfield is recorded. By proper arrangement of the various unrelatedincident fields, the difficulties of ill-posedness and nonlinearityare circumvented, and the permittivity distribution can bereconstructed through simple matrix operations. The algorithm is basedon the moment method and the unrelated illumination method. Numericalresults are given to demonstrate the capability of the inversealgorithm. Good reconstruction is obtained even in the presence ofadditive random noise in measured data. In addition, the effect ofnoise on the reconstruction result is also investigated.
