Electromagnetic Environment Test System Performance Test Specification

Electromagnetic environment is referred to the sum of all electromagnetic phenomena in a given place.Radio management and technical personnel of the former radio station set up for use in electromagnetic environmental testing,and proposes the use of frequencies and station settings recommendation,so as to solve the problem of mutual interference among radio stations.Therefore,the electromagnetic environmental test acts as a technical support in managing the radio stations scientifically and standardly.On radio station electromagnetic environment testing can be effective use of the radio spectrum.In order to facilitate radio regulatory agencies at all levels to carry out electromagnetic environment testing,electromagnetic environmental test system was configured accordingly,but the system is long-term,performance will change occurred in the outdoors.Therefore,radio management and technical personnel of the system performance of such systems for testing,calibration and validation.In order to improve the utilization of radio spectrum resources in our country and reduce the establishment cost station unit and the scientific management of spectrum resources,microwave electromagnetic environment testing is an important and difficult task.This thesis analyzes the electromagnetic environmental testing purpose and meaning,and then through the usual electromagnetic environment test systems and related core component modules introduced separately for factors that affect system performance will be elaborated.The microwave station electromagnetic environment is taken as an example to test in this paper.Finally,the accuracy and feasibility of system tests were demonstrated to get a set of methods to test performance index of the electromagnetic environmental test system.These methods can be used by electromagnetic environmental testing technicians.
