Rain and ice effects in satellite communication ppt. S kaur assistance professor dept of eloctronics communication engg ims engineering college ghaziabad presented by niranjan kumar ec 2 3rd yr 1114331107 oct 29 2014 satellite communication 1 2. Rain has been seen as a major source of interference on signal propagated for satellite communication at frequency above 10ghz nweke 2015. Effect of rain on satellite link above ku band. Of scrambling the received signal.

At c band 6 4 ghz rain has little effect except for brief periods of unusually heavy rain but at ku band 14 12 ghz it can be important. Et al other than rainfall the effect of hamartan sunshine and cloudy weather are investigated on the ku band for digital satellite television system. Rain fade refers primarily to the absorption of a microwave radio frequency rf signal by atmospheric rain snow or ice and losses which are especially prevalent at frequencies above 11 ghz it also refers to the degradation of a signal caused by the electromagnetic interference of the leading edge of a storm front. The presence of rain can have a significant detrimental effect on the propagation of an electromagnetic signal.

Characterizing rain rain distributes calculating alteration rain effects on antenna wise temperature ice crystal effects. The rain degradation increases as the frequency increases. Earth station design basic antenna theory parabolic antennas earth station subsystems monitoring control frequency co ordination vsat.

Radar radar factors affecting radar performance. The performance of a radar system can be judged by the following. Under the esteemed guidance ms.

Calculation of rain attenuation for higher frequencies under the guidance of dr. Rain fade can be caused by precipitation at the uplink or downlink location. 1 the maximum range at which it can see a target of a specified size 2 the accuracy of its measurement of target location in range and angle 3 its ability to distinguish one target from another 4 its ability to detect the desired target echo when masked by large.
