Kurzfassung
SAR Tomography (SARTom) is the natural extension of SAR Interferometry (InSAR) to solve for multiple phase centers within a resolution cell and obtain the 3-dimensional (3D) representation of a scene. This paper deals with the determination of the minimum number of tracks required to perform SARTom. Through the prolate spheroidal wave functions, the number of equivalent targets of a volumetric source is derived and from it, the minimum number of observations required to apply subspace super-resolution methods is computed. The minimum tomographic aperture length is also investigated. The results are validated on real data acquired in L-band by the E-SAR system of the German Aerospace Center.
