Ionspheric effects on radio propagation. A summary and selected analysis of ionospheric measurements in the rocket and satellite tracking programs of the US Army Ballistic Research Laboratories

This report is intended to be a very brief survey of work carried out by the U.S. Army Ballistic Research Laboratories in that portion of their upper atmosphere research program concerned with ionospheric effects on radio propagation. The thrust of this present effort has been the extraction and discussion of ionospheric effects on radio propagation which continue to be of importance in the performance and effectiveness of communications systems.
