Studies on the inter-relation of Ku-band scintillations and rain attenuation over an Earth-space path on the basis of their static and dynamic spectral analysis

► Rain attenuation and scintillations of Ku-band satellite signal have been studied. ► Signal fluctuations due to two phenomena are separated by filtering technique. ► Power spectra of low- and high-pass filtered data are compared with theoretical values. ► Wavelet spectra indicate that rain attenuation degradation is much larger than scintillation effects. ► A positive and non-linear relationship exists between the two co-occurring phenomena.
