摘要
Ka频段卫星通信中,降雨引起的信号衰减对通信链路的通断起着非常重要的作用.本文在阐述雨衰原理的基础上,分析了Ka频段雨衰对信道特性的影响,提出了Ka频段抗雨衰的各种对策,并通过实例说明了对策的有效性.
Rain attenuation has a significant impact on Ka-band satellite communication links. This paper analyzes in detail the principle of rain attenuation, the effect of Ka-band channel quality, and also proposes Ka-band anti-rain attenuation solutions. Effectiveness of the solutions is demonstrated through actual instances.
