FSV-based evaluation of electromagnetic scattering characteristics of deformed target

Many factors will cause obvious difference of the electromagnetic scattering characteristics of an aircraft when it is in its static state and in dynamic flying state. Shape deformation is such a factor which occurs during flying state. In this paper, the Feature Selective Validation (FSV) uses multiple quantitative qualitative indicators to evaluate the dynamic and static electromagnetic scattering characteristics of the flying target caused by shape deformation. The evaluation results of the amplitude difference measure (ADM), the feature difference measure (FDM), and the global difference measure (GDM) obtained by the feature selection verification method.
