A New Methodology Based on an Iterative Multi-scaling for Microwave Imaging
type: Article
abstract: In this work the problem of the localization, shaping and dielectric permittivity reconstruction of dielectric targets is addressed. The scatterers under test are inhomogeneous cylinders of arbitrary cross sections probed by a set of incident electromagnetic fields of TM type. The scattered field data are processed in order to locate and roughly recover the objects'shapes. Then the scatterers under test are reconstructed with an increasing accuracy by means of an iterative multi-scaling procedure until stationary reconstructions are ahieved. The proposed method is presented jointly with a modified conjugate-gradient inversion procedure in order to minimize the arising cost function. Howewer, this methodology is independent from the minimization algorithm and other and more efficient algorithms can be used. In order to assess the effectiveness of the iterative multi-scaling method, the results of several test cases (with and without noise) are presented and discussed in more detail. (c) 2003 IEEE.
