Abstract :
This paper describes a 3-D imaging technique employing a near-field inverse synthetic aperture radar, operated in a multi-static antenna configuration, to provide high resolution tomographic reconstructions of highly unstructured targets. The technique is based on spatially-variant Fourier-domain matched filters corresponding to spherical-targets of varying radius in a cylindrical-polar coordinate system.
