Abstract AR
لقد تم في هذا البحث انجاز برنامج متعدد الأغراض لتقدير التأثيرات السلبية الناتجة عن خليط عشوائي من دقائق الثلج المعلقة في الغيوم و الثلج الممزوج بالماء و قطرات المطر التي قد تعيق عمل منظومات الاتصالات عبر الأقمار الصناعية ذات الاستقطاب المزدوج.
هذا و قد تم حساب التوهين و فرق الطور و امتزاج الاستقطابين عند ترددات لم يسبق تناولها من قبل و لقد أخذ بعين الاعتبار في البحث اعتباران مهمان هما تأثير طبقة الثلج المعلقة على امتزاج الاستقطاب و تأثير الثلج المائع على التوهين الناتج عن المطر.
Abstract EN
A versatile Propagation Simulation Program (PSP) is developed to assess the degrading effects caused by the concurrent occurrences of an arbitrary mixture of ice plates and needles, melting snow and raindrops which may impede the reliability of dual-polarized satellite communications systems carrying independent channels on a single radio path.
Specifically, results are presented for the Cross Polarization Discrimination (XPD) due to ice and rain, differential attenuation, ∆α and differential phase shift, ∆ǿ, due to rain and average specific attenuation, ǿ, and phase shift, ǿ , due to the melting layer at hitherto unconsidered frequencies.
The inclusion of an ice-cloud medium is found to possess significant effects on rain-induced XPD even for low ice concentrations, particularly at low fade levels.
The relative contribution of the melting layer on rain-induced attenuation is extensively studied for frequencies from 1 to 100 GHz and rain rates below 20 mm / h.
