Abstract:
A computerized system for ballistic analysis comprisingmeans for comparing land impressions on the surfaces of a plurality of control bullets, fired by a suspect gun, to one another in all possible relative orientations for the control bullets; means for computing a correlation coefficient for each land-to-land comparison between the control bullets; means for identifying a set of matching coefficients corresponding to the correlation coefficients for each pair of the control bullets in a relative orientation of greatest match; means for identifying a set of non-matching coefficients; means for statistically evaluating whether or not the sets of matching coefficients and non-matching coefficients are statistically undistinguishable; and means for concluding the suspect gun is identifiable in response to a statistical evaluation that the sets of matching coefficients and non-matching coefficients are not statistically undistinguishable.
