Tomographic Reconstruction of the Index of Refraction Using Radar at 15 GHz

In this paper, we present a method for processing tomographic radar data with subsequent imaging. The imaging method we used is the averaged multiplicative algebraic reconstruction technique, which is commonly used for tomography purposes. We applied this technique to data measured at 15 GHz to reconstruct the index of refraction of an object. The results of this reconstruction are presented in this paper. Finally, we have developed a simple method that aims at correcting for signal paths which have been deflected due to refraction.
