Microwave imaging of multiple conducting cylinders using local shape functions

Abstract

A novel technique is presented for microwave imaging of multiple conducting cylinders using local shape functions. In this method, a scattering volume is divided into small sub-scattering regions and assigned a local shape function amplitude. The reconstructed image is represented by the set of local shape functions that satisfy multiple scattering boundary conditions. Monochromatic image reconstructions have a resolution scale of 0.1 lambda for single scatterers; multiple scatterers can be resolved at a separation of 0.42 lambda .< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
