To achieve electromagnetic signal recognition in complex environments,a specific emitter identification(SEI)method based on multi⁃feature parameter cluster analysis is proposed.By analyzing ten feature parameters related to emitter,establishing a specific emitter feature array,constructing a clustering equation,and using the separation between classes and intra⁃class clustering of electromagnetic signal parameters,the identification of specific emitter can be enabled.Theoretical analysis and experiments show that the multi⁃parameter calculation results of the expert scoring method are more discrete,which is a benefit to the identification of specific emitter.The research results provide strong support for promoting the development of electromagnetic signal detection and resolution technologies,and have technical reference value.
