Satellite beacon measurements at 12.255 GHz with an elevation angle of 40.1° during concurrent rain attenuation and tropospheric scintillation are analyzed. The power spectra density of the beacon signal is presented and scintillation are extracted from the raw propagation beacon data using a high pass filter with a cutoff frequency ranging from 2 to 500 mHz. It was observed at low frequency (2 mHz) the presence of rain attenuation in the scintillation time series that was absent at high frequency 850 mHz.
Key words: Tropospheric Scintillation, satellite communication, ku-band.
