WebIn radio astronomy, ionospheric and interplanetary scintillations lead to image wander, degradation of image contrast, pulse broadening of pulsar signals, angular broadening of point sources, and thus degradation of the resolving power of radio telescopes (Strom et … Web2 jul. 2014 · Tropospheric scintillation is a phenomenon that will cause signal degradation in satellite communication with low fade margin. Few studies of scintillation have been conducted in tropical regions. To analyze tropospheric scintillation, we obtain data from a satellite link installed at Bandung, Indonesia, at an elevation angle of 64.7° and a …
