Ambient Electron Density Profiles - Project SECEDE II

Abstract

Project SECEDE II was a series of high-altitude barium releases made at Eglin Air Force Base, Florida, during the period from 16 January to 2 February 1971. An RF transmission experiment using a rocket-borne beacon and four fairly widely separated ground-based receiving stations was one of several methods employed for making ion cloud diagnostic measurements. That function constituted the primary role of the RF transmission experiment. However, since the beacon rockets were programmed to fly behind the ion cloud, relative to the ground receiving stations, for only a short period of time when the beacon rocket was near apogee, a large amount of data for the ambient ionosphere was collected. A unique opportunity thus presented itself for making electron density measurements of the ambient ionosphere from data gathered over four widely separated propagation paths simultaneously. These measurements are the subject of this report.
