SOME CONSIDERATIONS ON IONOSPHERIC SELFMODULATION AT OBLIQUE INCIDENCE

Abstract

During the years 1957-1958 and 1959 some thirty experiments were made on the phenomenon of ionospheric selfmodulation at oblique incidence. Measurements made totalled 101,273 of which only 70,581 were of use. Various disturbances (interference from radiotelegraphic stations, defects of the camera) affected 22,504 and the remaining 8188 could not be used because of distortions due to the ionosphere. For the first time it was ascertained that it is possible to have overmodulation as well as demodulation and for this reason it was decided to call the phenomenon ionospheric selfmodulation instead of ionospheric selfdemodulation.
