The cratering process of a shaped charge jet is a complex phenomenon because the jet consists of a series of discrete particles that create separate craters within the target. The cumulative effects taking into account the contribution of all jet particles give the final penetration performance. For a theoretical analysis of the terminal ballistic performance of shaped charge jets, it is therefore necessary to measure experimentally the complete three‐dimensional motion of each jet particle. This can only be done by sophisticated techniques like for example Double‐Orthogonal Synchro‐Streak (DOSST) introduced by Held. Data from such experiments can be used as input for penetration models to calculate the penetration depths of jets. The model used for this analysis includes a description of the crater shape together with an appropriate selection algorithm to find the impact position of a single jet particle within the already formed crater profiles. The calculated values for the penetration performance are compared with the data provided by DOSST experiments from Held.
