An Ionosonde (Also known as a chirpsounder or ionospheric sounder) is a radar that examines the Ionosphere and monitors HFHigh Frequency (3-30 MHz) propagation conditions by sweeping the HFHigh Frequency (3-30 MHz) band and receiving the echoes.
Ionosondes sweep from 1-40Mhz. They send a line of very short pulses up the band. It looks like a slanted line when observed on a waterfall display.
Ionosondes are examples of Frequency-Modulated Continuous Wave (FMCW) based radar.
Frequencies[edit]
Ionosondes can operate at a range from 1 MHzMegaHertz (MHz) 10^6 Hz to 40 MHzMegaHertz (MHz) 10^6 Hz, however they primarily operate between 1.6 MHzMegaHertz (MHz) 10^6 Hz to 12 MHzMegaHertz (MHz) 10^6 Hz.
