Abstract-Carleton damage function has been commonly utilized to describe the weapon-target interaction in the weapon effectiveness analyses. This function is simplified from the actual weapon lethality data and these simplifications can affect the analysis results. This paper investigates the difference between results of Monte Carlo simulations to determine the probability of target damage that utilize the Carleton damage function and the results of the same simulations that utilize a non-simplified probability of kill (Pk) matrix. A problem of multiple shots of an unguided artillery weapon against an area target was chosen as a case study. Two sets of Monte Carlo simulations to determine the probability of damage on a target were performed for several numbers of shots and target sizes. The first set of simulations utilized the Pk matrix while the second set utilized the Carleton damage function. Statistical analyses were performed. It was suggested that there was difference between the results of two sets of simulations but the effect size was small.Index Terms-Damage function, probability of damage, Monte Carlo simulation, weapon effectiveness.
This paper describes a quick method to predict the impact point of an artillery rocket when it is equipped with a non-standard fuze and the firing tables and a fire control program supplied by the rocket manufacturer become no longer accurate. The method has been applied to a 122 mm artillery rocket that was originally designed to be used with MRV-U fuze but it was replaced by M423 fuze. Live fire tests of six rockets were conducted at a half range and a full range. The impact points were measured by a radar. From the test results, the average relative error of predicted range by the proposed method was -1.4% at half range and -3.3% at full range.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
