THE DETERMINATION OF WHISTLER EXIT POINTS FROM SPECTRUM ANALYSIS

In the propagation of VLF pulses in earth-ionosphere waveguide, the spectrums of pulses vary and frequency components of 2-4 kHz are absorbed seriously. According to the principle that the VLF pulse spectrums change with propagation distance, a new method is proposed to determine if whistler waves u...

Description
Summary:In the propagation of VLF pulses in earth-ionosphere waveguide, the spectrums of pulses vary and frequency components of 2-4 kHz are absorbed seriously. According to the principle that the VLF pulse spectrums change with propagation distance, a new method is proposed to determine if whistler waves undergo waveguide propagation before they are picked up. By analysing whistler spectrum of the South Pole, we can determine whistler exit points from this method. The results are in good agreement with that of other experimental method.
