Comparison of X-band satellite link measurements with radar derived rain attenuation in the tropics

The analyses concerning comparison between measured signals of RazakSAT’s Malaysian X-band satellite link and radar derived attenuation using an S-band meteorological radar is presented. Weather radars have been consistently used for investigating propagation phenomena which can affect satellite com...
