The Analysis Of Measurement And Interference Of Microwave Relay Station’s Electromagnetic Environment

In the radio management, the problems such as microwave relay station’s electromagnetic environmental measurement and interference are often met with. Microwave relay station’s electromagnetic environment refers to all kinds of electromagnetic radiation energy surrounding the microwave relay station, namely the source of interference. With the rapid development of technology and economy, the electronic technology and electromagnetic energy are widely applied in more fields, creating the increasingly complicated electromagnetic environment. The various kinds of electromagnetic radiations surrounding the microwave relay station may disturb the microwave relay communications, affecting the normal communications work. Therefore, the calculation of electromagnetic environmental measurement and interference before the microwave relay station is built has already become an important technological work in the procedure of examining and approving the wireless station.Firstly, this paper studied how to link the BER concerning digital microwave and Frequency Analysiser’s readings in the actual measurement. The permission value of disturbing signal can be brought out by setting up math model and analyzing and calculating, and ultimately combining the actual situation in the engineering application, which will be directly reflected in the Frequency Analysiser’s readings. This is the key to combine theory with practice.Secondly, the paper discussed how to make further analysis and calculation in accordance with the data measured by microwave electromagnetic environmental measurement system so as to bring out a direct and reliable result and ultimately form a more normal report in the analysis of microwave electromagnetic environmental measurement and interference. The purpose of forming the test report is to determine whether the preliminary station site meets the requirements for our country’s standards so as to guarantee the reliable communications after the microwave station is built and seek anti-interference measures when interference is found. The forming of the report in the analysis of microwave electromagnetic environmental measurement and interference is the ground on which the rate of frequency can be scientifically and reasonably assignment, which is also basic foundation on which the station units can set up stations.
