Photographic Records Showing the Variations of the Virtual Height of Reflection as a Function of the Radio Frequency
Entry ID:
gov.noaa.ngdc.G00551
Summary
Abstract:
ABSTRACT: The standard (analog) ionosonde produces photographic records known as ionograms, which show the variations of the virtual height of reflection as a function of the radio frequency. The frequency band normally used is from about 1 MHz to about 20 MHz though some ionosondes operate down to about 0.20 MHz and up to 30 MHz. The ionograms actually show the time of travel of the pulse signal ...
