Penyiaran satelit dalam jalur 21-GHz dijangka memancarkan isyarat berkapasiti besar seperti TV definisi ultra tinggi. Walau bagaimanapun, jalur ini mengalami pengurangan hujan yang banyak. Dalam hal ini, kami telah mengkaji teknik pengurangan hujan pudar, di mana kuasa sinaran meningkat secara tempatan di kawasan hujan lebat. Untuk mereka bentuk sistem penyiaran satelit sedemikian, adalah perlu untuk menilai ketersediaan perkhidmatan apabila menggunakan teknik pancaran meningkat tempatan. Data pengecilan hujan hendaklah diperoleh daripada data kadar hujan. Kami membangunkan kaedah untuk mengubah kadar hujan kepada pengecilan hujan dalam jalur 21 GHz. Kemudian, kami melakukan simulasi yang menggunakan kaedah untuk analisis ketersediaan perkhidmatan untuk contoh konfigurasi antena tatasusunan berperingkat. Keputusan mengesahkan ketersediaan perkhidmatan meningkat dengan teknik pancaran tempatan yang meningkat.

Abstract: Satellite broadcasting in the 21-GHz band is expected to transmit large-capacity signals such as ultrahigh-definition TV. However, this band suffers from large amounts of rain attenuation. In this regard, we have been studying rain fading mitigation techniques, in which the radiation power is increased locally in the area of heavy rainfall. To design such a satellite broadcasting system, it is necessary to evaluate service availability when using the locally increased beam technique. The rain attenuation data should be derived from the rainfall rate data. We developed a method to transform rainfall rate into rain attenuation in the 21 GHz band. Then, we performed a simulation that applied the method to the analysis of the service availability for an example phased array antenna configuration. The results confirmed the service availability increased with the locally increased beam technique.
