55051D – A Development of Computer Program for Estimating Probability of Target Damage for Multiple Launch Rocket Systems

view Abstract and Download
Abstract :   This paper presents the development of a computer program for determining the expected fractional target damage from a salvo of a multiple launch rocket system. The developed computer program utilizes a Monte Carlo method that simulates the impact points in thousand randomized runs. Then the results from these runs are statistically evaluated to determine the average expected target damage and the confidence interval. The program was tested with a problem, of which an analytical solution is available. It was found that the results from both methods were close. In addition, the program was tested in two additional case studies to investigate the number of Monte Carlo runs needed to provide reliable results.

56043D – A Comparison of Target Damage Estimation using Different Damage Functions for Multiple Launch Rocket Systems

Abstract :   This paper presents a comparative study on the results of Monte Carlo simulations that employ different damage functions to calculate the expected target damage caused by a salvo of a multiple launch rocket system. Four commonly used damage functions, i.e. cookies cutter, exponential, incline step, and log normal, were investigated. Three selected case problems with different type of targets showed that there was significant difference in the simulation results when using these damage functions with the same sure kill radius and sure safe radius. On the other hand, there was small difference in the results when using these damage functions, except the exponential function, with the sure kill radius and sure safe radius that results in equal lethal area.

57031J – Monte Carlo Simulations of Weapon Effectiveness Using Pk Matrix and Carleton Damage Function

view Abstract and Download
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.
