abstract

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.

8. Conclusion

The primary contribution of this paper is that a new evaluation method, based on error spectrum, is presented to the weapon systems accuracy. First, based on the correlation coefficient criterion, the new bootstrap method has faster convergence speed and lower square error than the bootstrap method under the small sample case. Second, more attributes of the weapon systems will be considered by using the error spectrum. Third, the above evaluation method can not only evaluate the similar weapon systems before and after improvement but also to rank the accuracy of the designed weapon systems to the other. Finally, simulation shows that the proposed evaluation method can efficiently handle the weapon systems accuracy problem. It is worth noting that the limitation of the proposed method is that the new evaluation method depends on the test data. As a future work, a possible direction is to put the presented method to the weapon systems evaluation.
