(3)As the grey GM (N, H) model has the characteristic of predictive power, this paper embedded GM (1, 1) model into the Calman filter method. The results show that, combined with the grey GM (N, H) model, Calman filtering model is well consonant with the observation data.                    (4)This paper studied a number of transient processes of explosive forming process in the eyes of detonation driving. This paper has shaped EFP into three parts: head, compact middle section, cracking tail section. Simulation of EFP explosive forming process from detonation beginning to the metal flow, liner collapse and forming penetrator was given. The EFP head length was estimated by means of simultaneous velocity model and Taylor angle model. The EFP length and diameter of compact middle section were estimated by means of fluid dynamics model. The tail cracking effect was estimated by means of material stress model.

Keywords: explosively formed penetrator, transient process, grey system, coupling error, normalization, global approximation, Calman filtering, gray GM (N, H) model, differential equation, detonation driving
