Abstract Aiming at the multi-point electromagnetic interference (EMI) radiation of the medical electronic equipment,this paper designs the analysis method based on the independent component analysis (ICA) algorithm.The near field time-domain signals,resulted from the superposition of multiple radiation sources,can be separated into several independent common mode and differential mode (CM/DM)radiation sources by applying the ICA algorithm.After the over standard sourceis found,technicians can take the corresponding improvement measures.Comparing to the present analysis methods,this one is more convenient and simple.It can quickly locate the over standard source and is easy to be manipulated and realized.In this paper,with three experiments,i.e.the double CM mixed source,the double DM mixed sources,and the CM/DM mixed source,the feasibility of the method is verified.And the validity of the method is tested by the application example in the electronic medical equipment.In the meantime,this method may offer a reference for tracing source in the complex electronic equipment and multiple radiation sources improvements in the future.
