Direction finding of auroral VLF hiss in auroral zone
A newly developed direction finding ('DF') for auroral hiss based on the measurement of time differences of wave arrival among three spaced points was carried out around Syowa Station (geomag. lat. -70.4°), Antarctica in 1978-1979. It has been found that the new DF can determine localized...
