Tomographic InSAR

Model-based tomographic applications (3-D discrete layers) were also developed for current SAR missions such as TerraSAR-X and Cosmo-Skymed but they require apriori information or assumptions. Kepler is presently developing a ground-based full Tomographic SAR system (no apriori assumptions about targets distributions).

Kepler developed the full SAR transfer function that includes the effects of the sub-pixel location of a radar target, for multiple targets within a pixel. InSAR is a particular (and operational) case of tomography.
