## What is 无线电计算器?

无线电计算器
实现：
1 无线电功率及场强单位的换算，考虑到阻抗；
2 根据无线电发射机功率，天线增益以及馈线损耗等计算EIRP；
3 根据接收机输入端的电平值以及天馈线参数计算场强值；
4 根据带宽，调制方式，信息类型，复用性质等计算发射标识。

Radio Calculator
Features:
1 Unit Conversion of Power and Fieldstrength,Impedance considered;
2 EIRP calculation based on transmitter power, antenna gain and feeder loss;
3 Convertion between received Level and Fieldstrength;
4 Designation of emissions calculation based on bandwidth, modulation, type of information, multiplexing and etc.
