| Abstract: | Reconstruction of two-dimensional medium target is an advancing field. Based on the Fourier diffraction projection theorem, specific reconstruction of algorithm of microwave imaging is studied, and the resolution is discussed. In a weak dielectric contrast case, the forward scattered fields is be simulated with the computer by Moment Methods and the imaging of a cylinder is be reconstructed. A project in laboratory has been given to. |
