Abstract : Techniques of determining electron densities in the D region of the ionosphere from rocket measurements of field quantities of a CW radio wave transmitted from the ground are described. Iterative methods which are based on a full wave solution of the generalized form of the differential equations governing radio wave propagation in the ionosphere are used to analyze data from two rocket flights at Ft. Churchill, Manitoba, Canada. The results of one flight (July 20, 1963) during a solar eclipse are compared with electron density profiles obtained from an impedance probe flown on the same rocket and from Langmuir probes flown in other rockets about the same time. The data from the second flight (July 26, 1963) was used to qualitatively verify the results of an impedance probe in the same rocket. The methods of analysis have also been applied to data obtained in the nighttime D region by Mechtly (1962), and the electron density profiles obtained by this analysis are presented. (Author)
