Popis:	The new technique of measuring radial expansion of a crater as a function of time on a shaped charge jet that penetrates water is explained in this paper. Radial expansion of the crater in the frame of experimentation can, in this case, be easily described with a modified Bernoulli equation under the condition that target strength is weak, the initial radial crater velocity is equal to the axial crater velocity and that the pressure p diminishes from the initial impact pressure p0, with the ratio of the area a to the initial area a0 of the impacting jet.
