AURORAL RADAR EQUIPMENT AND CHARACTERISTICS OF RADAR AURORA AT SYOWA STATION, ANTARCTICA
The observation of aurora by the radar method was carried out at Syowa Station in Antarctica during a period from April 1966 to December 1967. Instrumental outline and characteristics of the radio aurora are discussed in this paper. Results of this analysis are as follows : 1. The diurnal variation...
