Weapon systems accuracy evaluation using the error spectrum

Weapon systems accuracy is a vitally important tactical and technical index, which has a significant impact on the process of the weapon systems design and test. Based on different accuracy criteria, we proposed a new evaluation method for the weapon systems accuracy. First, a new bootstrap method, using the correlation coefficient criterion, is presented to evaluate a weapon systems accuracy when the sample size n satisfied n≥10. Second, measures for weapon systems accuracy are introduced to represent the different performance of weapon systems. Furthermore, an attributes matrix is proposed to combine the above measures. Third, inspired by the Pitman's closeness measure, we designed a weapon systems accuracy attributes competition matrix to contain the entire pairwise competition results, and then its positive eigenvector is employed to the weapon systems accuracy evaluation. Finally, a numerical example is provided to illustrate the effectiveness and feasibility of the proposed method. It is shown that the new evaluation method can not only evaluate the weapon systems accuracy before and after improvement, but also rank the accuracy of the designed weapon systems to the evaluated weapon systems.
