High Frequency Radar

High Frequency Radar for Measuring Ionospheric Propagation Conditions

Developed for monitoring HF propagation conditions.
HF digitizing receiver.

  • DC-30 MHz
  • DDS tuning, 0.1 Hz resolution
  • 15 KHz of instantaneous bandwidth
  • IQ demodulation
  • 2 channel, 16 bit digitizers
  • GPS time controlled
  • Motorola DSP 56302 processor


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.
