Hit accuracy is an important index for assessing the performance of missiles. For the accuracy assessment of anti-ship missiles, the hit probability is usually used as the accuracy index. In the process of assessing the accuracy of anti-ship missiles, different assessment methods may bring inconsistent results when using the classical method. In order to improve the consistency of the evaluation results and reduce the risk of assessment, we improve the hit-precision estimation method based on normal distribution and propose a new method of interval estimation of hit probability based on Bootstrap resampling. Then we combine the hit-accuracy evaluation method based on binomial distributions for consistent analysis and evaluation of hit accuracy. Compared with the classical method, the proposed method reduces the risk of assessment and improves the robustness of the assessment results.
