Electrical Measurement of Microwave Current and Its Calculation

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 of obstacle can be calculated after the determination of obstacle location, by using both the height - loss curve and the formula of diffraction loss.
