Abstract
This study undertakes the determination of
suitable cutoff frequency for extracting scintillation amplitude
dataset from radio propagation beacons on satellite link within
Akure (7.17oN, 5.18oE), Southwest Nigeria. Attempt was also
made towards evaluating the spectral characteristics of
scintillation parameters through power spectra density (PSD)
analysis. Concurrent measurement of satellite beacon signals
and meteorological parameters was carried out on Earth-space
path over the location for tropospheric amplitude scintillation
studies. Tektronix Y400 NetTek Analyzer and Davis Vantage
Vue weather station were used for beacon and weather
parameters measurements at 1 second and 1 minute
integration times respectively. Data spanning one (1) year of
measurement were used for the investigation. Results show
that extra contributions to signal distortions by nonscintillation
mechanisms during extraction of scintillation
dataset from satellite radio beacon series may be eliminated by
using a cutoff frequency, fc of 0.25 Hz for high pass filtering.
Also, spectral slopes with lower magnitudes were found to
occur more predominantly than those with higher magnitudes
