INVESTIGATIONS OF PROPERTIES OF THE AURORAL ZONE IONOSPHERE BY MEANS OF A RADIOASTRONOMICAL SWEPT-FREQUENCY INTERFEROMETER, COVERING THE FREQUENCY BAND 35-65 MC/S.

Results obtained with the help of a radioastronomical swept-frequency interferometer at Kiruna Geophysical Observatory during the months March - December, 1961, are discussed. A special type of increase of the broad-band radiation intensity of the radio-source Cassiopeia has been observed. This seem...

Description
Summary:Results obtained with the help of a radioastronomical swept-frequency interferometer at Kiruna Geophysical Observatory during the months March - December, 1961, are discussed. A special type of increase of the broad-band radiation intensity of the radio-source Cassiopeia has been observed. This seems to result from the focusing effect of single ionospheric regions of a size larger than the first Fresnel zone. An investigation of correlation of the increases with other geophysical parameters has also been made. (Author)
