OPERATION SUN BEAM, SHOTS LITTLE FELLER II and SMALL BOY. Project Officer's Report - Project 7.16. Airborne E-Field Radiation Measurements of Electromagnetic Pulse Phenomena

Abstract

Airborne measurements of the absolute vertical electric field (E- field) of the radiated electromagnetic pulse were attempted for Shots Little Feller II and Small Boy. Instrumentation included calibrated vertical whip antennas, wideband magnetic tape recorders, and photographs of oscilloscope traces. One instrumented aircraft participated in Little Feller II (C-131F); two aircraft participated in Small Boy (a C-131F and an A-3A). No detectable signals were recorded for either event. It is concluded that the vertical E-field intensities encountered were below the calibrated levels of the instrumentation or the method of instrumentation and calibration was inadequate for nonrepetitive pulse signals.
