Description
Summary:P(論文) A 50MHz auroral doppler-radar was operated at Syowa Station, Antarctica, in 1978 in cooperation with sounding rocket experiments during the International Magnetospheric Study. E-region irregularity-drift was measured by the radar while electric field, electron density fluctuation and other parameters were measured by the rockets. Electric field components perpendicular to the radar wave-vector, which were derived from the doppler shifts of echoes, are compared with in situ electric field measurement to find a qualitative agreement between both results. Sharp peaks due to the two-stream instability were found in echo spectra. The radar echo intensity seems to be dependent on the drift velocity of irregularities. departmental bulletin paper
