Rain effect on ku-band satellite system

الملخص EN

Satellite system has many frequency bands, Ku-band is the most used bands in satellite services like DVB, DAB, Internet.

The ionosphere influences specially, Rain along the transmission path is the major weather effect of concern for satellite communications operating at frequencies above 10 GHz.

Raindrops absorb and scatter radio wave energy, which degrades the reliability and performance of the communication link.

Rain effects are dependent on frequency, rain rate, drop size distribution and drop shape, which are determined by the type of rainrain has the direct effect on the satellite signal and causes decrease in the received signal.

This paper is an attempt to study, calculation of rain effect in Iraqi Kurdistan region.

As shown in the results presented that the horizontal polarized signals affected more than vertical polarized signals, also, the location of the earth station.

This paper give the simulated data bout the rain effect in Iraqi Kurdistan region for the five Governorates in order to compensate the loss caused by the rain.

Finally, some solutions and recommendations presented to reduce the rain effect hope be useful for any satellite system users in any locations to minimize this effect, improvement and increase in the received signal.
