Observations of amplitude scintillations on a low-elevation earth-space path

Results of ammplitude-scientillation measurements at 11 GHz on an 8.9-deg elevation path from an Intelsat V satellite are presented and briefly compared with those obtained from OTS at 30-deg of elevation. The variability of the standard deviation of the process is illustrated and discussed in the context of the long-term distribution. Spectral density analysis reveals the familiar bandlimited noise type of spectrum with a 3 dB corner frequency of about 60 mHz.
