High Resolution Computerized Ionospheric Tomography Systems.

Abstract

The research funded by this grant is for the investigation of computerized ionospheric tomography as a method for characterization of the ionosphere. This research looks at specific degradation factors and develops compensation techniques and new CIT algorithms that mitigate or minimize their effects. Research has progressed in three categories: design and analysis of a time-varying algorithm to remove the resolution degradation effects caused by ionospheric motion, investigation of localized algorithms to compensate for the angular restrictions of the CIT system and the development of a CIT algorithm and system testing suite. Of note is the research into the effects of ionospheric motion on CIT reconstructions. It was shown that even simple linear motion can resulting significant errors in peak height estimates using CIT algorithms which do not account for the motion.
