range beacon

doppler very high frequency omni-range beacon

多普勒高频全距离信标

The feasibility analyses for LED to be used as the luminous device of beacon lamp have been completed through the analyses of the operating range and the luminous intensity of LED.

从LED的作用距离分析和发光强度分析两方面完成了LED用作标志灯发光器件可行性的理论分析。

It can be used in developing the short range radio navigation ground beacon and testing the performance of its transmitter.

该平台可在近程无线电导航地面导航设备的研制中确定发射机参数和检验性能时使用。

By this method, if the reading on attenuater and the distance between the radar beacon and the laboratory are know, the maximum range of radar beacon can be calculated.

利用此法，只要知道衰减器的读数和试验点离实验室的距离，就可计算出雷达信标的最大作用距离。
