Comparative study of SAR tomographic reconstruction algorithms

Synthetic Aperture Radar (SAR) tomography can reconstruct the elevation profile of each pixel based on a set of coregistered complex images of a scene. Its main advantage over classical interferometric methods consists in the capability to detect multiple target contributions within the same pixel. In this paper, three tomographic algorithms are compared and applied on a dataset of 32 images to generate the elevation map of dominant scatterers from a scene.
