1) antenna efficiency 天线效率1. Antenna system noise temperature and antenna efficiency are the most important items in the system debugging and checking before the VLBI observation. 在流动VLBI的观测试验中 ,天线系统噪声温度和天线效率是观测前系统调试和检测的两项重要内容。
Being a ratio, antenna efficiency is a number between 0 and 1. However, antenna efficiency is commonly quoted in terms of a percentage; for example, an efficiency of 0.5 is the same as 50%. Antenna efficiency is also frequently quoted indecibels (dB); an efficiency of 0.1 is 10% or (...

在举一个例子,假设一个天线效率Efficiency为50%,那转成dB是多少dB呢? 20log(0.5)= -6dB or 10log(0.5)=-3dB 一样天线效率的定义是什么?天线效率是输入功率Pin与输出功率Pout的比值,有看到关键字功率(Power)吗? 所以当然天线效率就是要用10log来计算为10log(0.5)=-3dB。
