PROPAGATION CHARACTERISTICS OF MICROPULSATIONS.
Abstract
Simultaneous earth current measurements were made during August and September, 1965 at Ashland, Maine; Huancayo, Peru; Dillingham Air Force Base, Hawaii; and Manila, Philippines. The purpose of the measurements was to provide accurate, reliable data for a study of the worldwide propagation of micropulsations. A method was developed to estimate, by computerized analysis of the data, the difference in arrival time of coherent energy (group delay) at the respective stations. The accuracy limits imposed upon these measurements by the equipment and local geologic conditions have been investigated. Confidence levels of coherence were examined. A method of measuring differences between stations of polarization sense and direction has been derived.
