| 總結: | Ku-Band signal is often used for satellite communication mainly for direct to home (DTH) broadcasting. One of the major issued using this band is that the signal will be affected by raindrops. Raindrops absorb and scatter the signal that operates more than 10 G Hz. However, there are studies were done to predict and measure the rainfall rate and rain attenuation. The rain attenuation in Ku-Band range and the rain rate were measured at the satellite receiving dish, pointed towards the orbital slot 91.5 E over a one year period (2013). The cumulative distribution of rain rate obtained as well as a cumulative distribution of rain attenuation obtained are presented and compared with the rain prediction models. The aim is to get the best model to be used for the purposed of software development. It was found out that the DAH predictions model is fairly equitable when compared with direct satellite dish receiving measurements in Malaysia. The model provided a suitable baseline in developed a user interface software for weather forecast prediction. The method of designing the software were using the QtSDK. The metadata of the software is gathered from MMD andNOAA. |
