Abstract: Electromagnetic pulses (EMP) are capable of causing effects like malfunctions, performance degradation, interferences, and destructions in electronic and electrical systems. The EMP effect simulation is one of key points from home and abroad. Furthermore, EMP coupling is the promise and foundation of effect evolution and protection. In this paper, a new method, based on the combination of system identification theory and Volterra series algorithm, was proposed for the analysis of the EMP electromagnetic coupling phenomena from an external field to an inner electric system. In particular, we focused on the ultra wide band (UWB) pulses, which were able to cause malfunctions or even destructions of complex electronic systems and the coupling effect has not yet been sufficiently analysed. Based on experience data, we designed a new method using Volterra series to identify EMP electromagnetic coupling model. We firstly analysed the theory foundation of non-parameters model evolution. And then, to verify the validity of this method, we designed UWB pulses electromagnetic coupling table and gained radiation coupling data. Finally, model testing results showed that the increased model accuracy and smaller computation will improve EMP effect evolution, also which can apply this method to EMP electromagnetic coupling model identification.
