Based on the electromagnetic scattering, coupling effect and the theory of vector transmission, combined with the demands of the coupling group electromagnetic characteristics of air combat and the theory deficiency, the technical route of electromagnetic scattering simulation based on the theory of vector transmission is proposed, and the theoretical model of coupling group in complex air environment is established. In addition, the electromagnetic scattering imaging of typical aerial platform targets and interference groups are studied. Through the simulation calculation of the coupling effect and the numerical simulation of the spatial distribution of the typical air flow field and the dynamic spatial distribution of the coupling group, the simulation analysis of the spatial coupling effect of the jamming material is carried out. It provides the theoretical and simulation model supports for improving the survivability of the weapon platform and the application of interference in the complex electromagnetic environment of the air battle field.
