Abstract: Modeling and decladding corrections are adopted to research the edge effect of shell inthe quantitative inspection of charge density of medium and large caliber ammunition by industrial CT imaging. The accuracy of density comparison model can be improved. The test results show that the accuracy of decladding correction methodis better than that of modeling correction method for charge density inspection of ammunition. The proposed methods can be used for the inspection of local charge density by industrial CT imaging.

Key words: ordnance science and technology, industrial CT, charge density, edge effect, quantitative inspection, beam hardening, beam scattering
