Abstract
The report describes a novel method for characterizing the fragmentation of explosive munitions. Three experiments are performed simultaneously during the static detonation of munition: a 35-GHz radar is used to measure to Doppler power spectrum of the fragmenting munition; a second radar in the same frequency band provides information on the cross section and drag characteristics of individual fragments; sampling fragments by means of collectors given information on their spatial mass distribution. Fifteen tests are carried out in order to obtain statistically accurate results. The experimental results together with the analytical prediction of a hydrocode are then expressed in terms of a set of linear equations and stochastic programming code is used to optimize a solution for the number of fragments in joint classes of mass, velocity and projection angle based on minimization of errors and maximization of entropy.
