High Frequency Radar for Measuring Ionospheric Propagation Conditions

Summary

This is a high frequency (HF) radar receiver which digitizes WWV time broadcasts in order to monitor ionospheric propagation conditions. After digitizing the time broadcast, the receiver then stores the data on a host computer. This project was developed with the Physics and Astronomy Department at Western Kentucky University.
