Abstract: | The use of Ka Band (20/30 GHz) for future satellite communications has been addressed. The exploitation of Ka band with a
bandwidth of 2500 MHz seems to represent the largest significant achievement in satellite communications potential, so far.
The problems associated with the use of this frequency band such as attenuation and receiver noise temperature (floor) variation
with rain has been addressed. The receiver noise floor variation with rain has so far been ignored. Therefore, in view of
propagation and noise study over this Ka Band, both signal attenuation and receiver noise floor variations with rain rate
are estimated using dual frequency radiometers operating at 22.235 and 31.4 GHz over a tropical station, Calcutta, India. |
