EXPERIMENTAL PROGRAM TO DETERMINE PROPERTIES OF IONIZATION WHICH IS PRODUCED BY SPACE VEHICLES
Abstract
Research on deter ining the density, duration, and extent of ionization produced in t e ionosphere by artificial satellites and space vehicles is summarized. Theoretical analysis of single-frequency artificial earth-satellite radio transmis ions provided basic e uati ns and methods for gaining information concerning the electron density at the satellite. Analyses of such phenomena a magnetic disturbances, ionospheric irregularities, and satellite signal scintillation were accomplished. Other studies, such as expecte high-frequency reflection from suggested distributions around the satellite, were evaluated. The ionosphere seems to possess irregularitie that sometimes scintillate the signal from the satellite so greatl that it is impossible to measure the rate of Faraday rotation. Thi scintillation has a high degree of correlation wit pread F and sporadic E, but only a low amount of correlation wit magnetic and solar indices. More research is needed on the electron density of the ionosphere and its variations. There appears to be a possibility that satellite-ionosphere interactions, especially during periods at high geomagnetic activity, will create a disturbance having a large radar echo area. (Author)
