Wave Disturbance Radio Observations in the Ionosphere Associated with the August 1, 2008 Partial Eclipse
Quasi-periodic variations in the power of incoherently scattered signals generated by wave disturbances in the ionosphere are analyzed on a reference day and on the day of a partial eclipse that provided approximately 0.42 coverage. The spectral analysis techniques employed the window Fourier transf...

| description | Quasi-periodic variations in the power of incoherently scattered signals generated by wave disturbances in the ionosphere are analyzed on a reference day and on the day of a partial eclipse that provided approximately 0.42 coverage. The spectral analysis techniques employed the window Fourier transform, the adaptive Fourier transform, and the wavelet transform. The spectral characteristics within the 100÷500 km altitude on the day of eclipse and on the reference day are shown to differ appreciably. The spectral content starts to change at the beginning of the phase of maximum coverage and lasts for at least for 2 hours. |

Burmaka, V. P. Chernogor, L. F. Quasi-periodic variations in the power of incoherently scattered signals generated by wave disturbances in the ionosphere are analyzed on a reference day and on the day of a partial eclipse that provided approximately 0.42 coverage. The spectral analysis techniques employed the window Fourier transform, the adaptive Fourier transform, and the wavelet transform. The spectral characteristics within the 100÷500 km altitude on the day of eclipse and on the reference day are shown to differ appreciably. The spectral content starts to change at the beginning of the phase of maximum coverage and lasts for at least for 2 hours. Анализируются квазипериодические вариации мощности некогерентно рассеянных сигналов, вызванные волновыми возмущениями в ионосфере, в день частного (фаза около 0.42) солнечного затмения и в фоновый день. Для спектрального анализа использовались оконное преобразование Фурье, адаптивное преобразование Фурье и вейвлет-анализ. Показано, что в день солнечного затмения и в фоновый день спектральные характеристики волновых возмущений в диапазоне высот 100÷500 км заметно отличались. Изменения спектрального состава начинались после наступления фазы максимального покрытия диска Солнца и продолжались не менее 2 ч.
