ATTENUATION OF ELECTROMAGNETIC RADIATION THROUGH AN IONIZED MEDIUM

Abstract

The attenuation of electromagnetic radiation of various frequencies due to propagation through an ionized cloud was measured and the rate of removable of electrons by recombination and attachment from the attenuation measurements was computed. Radio signals propagated through an ionized cloud for yields up to 9.6 kt, from one to four minutes after the detonation, were not attenuated. An M-33 X-band fire-control radar skin-tracked an FJ aircraft through the ionized cloud created by a 40-kt detonation. No difference is signal level was noted whether or not the ionized cloud was interposed between the radar and the aircraft.
