摘要
卫星信号转发系统是将卫星信号转发至被遮挡区域的设备,当前市售的卫星信号转发系统存在输出功率明显高于卫星落地信号的"过度转发"现象。提出了采用可变增益放大器、赋形转发天线和分路器相结合的方法实现较大区域的"真实转发"的途径,并给出了设计原则和图表,对"真实转发"要注意的用户接收天线角度的设置、转发系统的标校等主要问题进行了探讨。
Translating system is used to radiate satellite signals to a shielded area. Signals radiated from translators in the market today are always too strong, compared to the real satellite signals, called ＂over translating＂. A new approach called ＂Exact translating＂ is proposed here, which comprising variable gain amplifier, beam deformed translating antenna and signal splitters. Charts and formulas to design such system are given. New concepts of how to orient customer antennas and how to calibrate the system are mentioned, which is very important for ＂Exact translating＂.
