| 摘要: |
| 为利用仿真模型在有限校射样本的条件下对校射补偿量进行合理估计，对考虑仿真可信度的舰炮虚拟校射方法进行了研究。对自适应加权贝叶斯估计方法进行了研究，一方面对仿真先验可信度的计算方法进行了分析，另一方面对考虑先验可信度的自适应加权贝叶斯估计算法进行了研究。在此基础上，结合舰炮虚拟校射的原理和需求，建立了舰炮虚拟校射诸元误差自适应加权贝叶斯估计模型。仿真验证表明：自适应加权贝叶斯估计方法能够利用试验数据对仿真模型的可信度进行有效验证并进一步实现对目标分布的有效估计；所设计的校射方法能够综合利用仿真模型和校射样本的优势，实现对诸元误差的合理估计，达到有效提高校射精度的目的。 |

| Abstract: |
| To estimate the compensation value reasonably with simulation model under the situation of limited data of proof shooting, the virtual proof shooting method for naval gun considering the reliability of simulation was studied. The adapted weighted Bayesian estimation considering the reliability of simulation was studied. On the one hand, the method for calculating reliability of simulation was analyzed; on the other hand, the adapted weighted Bayesian estimation algorithm considering reliability of simulation was studied. On the basis, considering the principle and requirement of virtual proof shooting, the model for estimating error of firing parameters based on the adapted weighted Bayesian estimation considering reliability of simulation was built. The results from simulation shows that: the adapted weighted Bayesian estimation considering reliability of simulation can verify the reliability of the simulation model efficiently with the test data, thus estimating the target distribution efficiently; the proof shooting method can use the advantages of simulation model and shooting specimen, and realize the reasonably estimation for error of firing parameters, and then, achieve the goal of effectively improving the accuracy of proof shooting. |
