The problem of imaging three dimensional perfect electric conducting objects from scattered field measurements is addressed. A multifre-quency/single view configuration in far-field zone is considered. The Physical Optics (PO) approximation is adopted to simplify the scattering model and the scatterers' shapes (i.e. their contour surfaces) are described as the support of delta distributions. This...
The problem of localizing small scatterers is dealt with. In particular, the time-reversal MUSIC and the linear distributional approach are compared from the achievable resolution and the stability against the noise point of view. The study is conducted for a two-dimensional and scalar geometry and for the case of perfect electric conducting scatterers.
The problem of localizing small inhomogeneities from the knowledge of their scattered field is dealt with. In particular, the case of small perfect electric conducting spheres is of concern, with the scattered field data collected under multistatic/multifrequency/single-view or multistatic/single-frequency/multiview far zone configurations. The multiple scattering between the spheres is neglected,...
