Abstract


Quasiperiodic power variations of incoherent scattered signals in the altitude range of ~100-500 km were analyzed for the partial solar eclipse day (magnitude about 0.78) and the control day. The windowed Fourier transform, adaptive Fourier and wavelet analysis for the system spectral analysis were used. The spectral characteristics of signal quasi-periodic variations were demonstrated to be significantly different in the eclipse and control days. The eclipse was accompanied by wave generation with the predominant period of 40-60 min, relative amplitude of electron density disturbance of 10-15% and duration of about 3-4 hours.
