Tomographic 3D Reconstruction From Airborne Circular SAR

This paper analyzes the potential of Circular SAR to perform tomography of semi-transparent media. In [1] it was shown that both sub-wavelength resolution and 3-D confocal imaging were possible using circular apertures. Since then, several airborne experiments have been performed showing the potential of such geometries [2, 3, 4]. In this contribution, real data acquired at L-band by DLR’s E-SAR sensor will be used to further analyze the high resolution and tomographic capabilities of circular SAR
