Inversion of Integral Transforms in Emission & Transmission Tomography and Synthetic Aperture Radar

 

Can Evren Yarman



Abstract:
In this talk I will summarize my Phd and Postdoctoral work on inversion of integral transforms in emission &transmission tomography and Synthetic Aperture Radar. In transmission and emission tomography, I will present  inversion of Radon & Exponential Radon transforms using non-commutative harmonic analysis.  In Synthetic aperture radar (SAR), I will start by presenting inversion of ideal case for monostatic SAR that traverses straight flight trajectory. Using the symmetries, this case can be modeled using circular averages transform and can be inverted using non-commutative harmonic analysis over the sphere. This will be followed by SAR imaging in the case of non-ideal scenarios, where I will present filtered backprojection type reconstruction algorithms for monostatic SAR, bistatic SAR and synthetic aperture imaging using sources of opportunities.
