Evaluation of high hitting accuracy performance of hypersonic vehicle

为科学合理地评估高超声速飞行器的命中精度,提出了一种基于误差谱的高超声速飞行器命中精度高准确度评估方法。对获得的高超声速飞行器命中精度数据进行预处理,得到该数据的落点偏差。构建算术平均误差、均方根误差、调和平均误差、误差中位数、误差众数、几何平均误差和迭代中距误差评估指标来反映高超声速飞行器命中精度的性能。分别建立高超声速飞行器命中精度评估模型及其可信度模型。通过实例验证所提评估方法的正确性和合理性。仿真结果表明:所提方法不仅能给出高超声速飞行器命中精度的评估结果,还能给出该结果的可信度。研究工作为高超声速飞行器命中精度的高准确度评估提供了新的科学评估方法。

To evaluate the hitting accuracy of hypersonic vehicles scientifically and reasonably,this paper proposes a high accuracy evaluation method using the error spectrum.First,the hit accuracy data of hypersonic vehicles are preprocessed to obtain the relative distance error.Secondly,the root mean square,average Euclidean error,harmonic average error,median error,error mode metric,geometric average error and iterative mid-range error are constructed to reflect the hitting accuracy of hypersonic vehicles.Then,we build the high accuracy evaluation model and its credibility model for hypersonic vehicles.Finally,two examples are given to verify the correctness and rationality of the proposed method.The simulation results show that this method can obtain not only the result of the hit accuracy evaluation,but also the credibility of the result.This research provides a new scientific evaluation method for evaluating high hitting accuracy of hypersonic vehicles.
