Electromagnetic compatibility optimization of the load/environment test system of a type of UAV

摘要

In the load/environment parameters test of some type of unmanned aerial vehicle,the test system endures serious challenges,because the equipment compartment is very small,there are a great many devices,and the electromagnetic environment is very complicated.On the basis of the analysis of the electromagnetic interference source,an electromagnetic interference matrix model of airborne test equipment is constructed in this paper.By utilizing some methods in the design,like grounding,shielding and optimizing the cable wiring,the electromagnetic compatibility can be effectively improved,and the influence of the electromagnetic interference is effectually reduced,which guarantees the compatibility between test system and aircraft system.
