Distance measurement method of fully-anechoic chamber for unmanned aerial vehicle data link

The effective operating distance of data link is an important character of an unmanned aerial vehicle(UAV).Accurate and effective testing of effective operating distance is of great significance for UAV flight safety and system reliability.With the detailed analysis of the components of transmission loss in UAV data link communication,the advantages and disadvantages of the current main test methods are compared from the aspects of test environment controllability,test efficiency,repeatability,and application task proximity.The indoor distance test method is designed and tested accordingly,and the relationship between effective communication distance and actual business applications is discussed through throughput metrics.The proposed method is more accurate and simple,which has strong practical value.
