Electromagnetic Measurements Conducted by the Central Radio Propagation Laboratory During Operation Upshot-Knothole (Redacted)

Abstract

This report describes the electromagnetic measurements conducted by the Central Radio Propagation Laboratory during Operation UPSHOT-KNOTHOLE. Pulse waveforms recorded at the Nevada Proving Ground reveal the original pulse shape before being distorted by the effects of propagation. Records made at distances of 1 to 3,000 kilometers show the changes in waveforms brought about by propagation. Attempts were made to interpret the waveforms received at distant stations in terms of active modes of propagation, and to relate the bomb yield to propagation distance, electromagnetic field strength and energy, detonation height, etc. Expressions are also given relating the attenuation of the pulse to propagation distance.
