微波电路电测及其计算方法

从实际工程的角度出发，对电路电测方法进行了论述。在微通信工程中，需要获得障碍物的位置和高度，最合理的天线高度组合和障碍物绕射损耗等参数，为此论述了微波电路电测方法及技术要求。在大庆－秦皇岛输油管道通信工程中采用了Ａ，Ｂ测试法进行测试，得到高度－损耗曲线。这种曲线给出相对自由空间接收电平与收，发天线高度之间的关系。在测试所得的高度－损耗曲线与断面图相结合的基础上，由绕射损耗计算公式推出了几种常见障碍

Electrical Measurement of Microwave Current and Its Calculation Method.

The article discusses the measurement of microwave current from the point of view of practical project. It is necessary for the design of a microwave communication project to know such parameters as location and height of obstacle, proper arrangement of antenna height, obstacle diffraction loss, ect. , therefor, electrical measuring method and technical requirement of microwave are introduced. In the communication project for Daqing - Qinhuangdao Oil Pipeline, A,B measuring method is used, and the location of obstacle is determined by deriving from formula the diffraction losses of several obstacles, based on the combination of height-loss curve and cross-section diagram. The height o:f obstacle can be calculated after the determination of obstacle location,by using both the height - loss curve and the formula of diffraction loss.
