First demonstration of airborne SAR tomography using multibaseline L-band data

In this paper for the first time the successful experimental realisation of airborne SAR tomography is demonstrated. The authors present the concept of aperture synthesis for 3D-imaging for the case of the multibaseline imaging geometry and discuss the limits arising from the limited number of flight tracks and their irregular spatial distribution. Finally they address the experimental requirements for SAR tomography and show some experimental results using a multibaseline data set acquired in L-band by DLR´s experimental SAR (E-SAR) on a testsite near Oberpfaffenhofen/Germany
