电磁轨道炮具有快速响应、高超音速、高毁伤效率等特点，是未来地面火力保障任务的一种很有前途的候选武器系统。由于发射过程中耗电量巨大，应优先考虑精确打击。EMRG射击精度是评价EMRG外弹道性能的一项重要性能指标，它是指弹丸落点与目标的贴近程度。为了给射击精度的测量提供一个系统的解决方案，详细地制定了评估因素。在此基础上，提出了包括弹道仿真、数据预处理、参数估计和命中概率计算在内的评估EMRG射击精度的总体框架。针对弹道模拟实验的耗时问题，提出了一种新的多准则最优拉丁超立方体设计方法，以保持实验时间和采样性能之间的平衡。最后，利用所设计的框架和提出的实验设计方法，对16公斤重弹丸的射击精度进行了评估。结果表明，在当前定义的情景下，圆形误差概率约为5公里，这意味着初始扰动可能会对没有制导和控制单元的弹丸的射击精度产生很大影响。
Electromagnetic railgun (EMRG) is a promising candidate weapon system for the future surface-fire support mission characterized by quick response, hypersonic velocity, and high damage efficiency. Since the huge power consumption during launching, priority should be given to the precise strike. Firing accuracy of EMRG, which refers to the closeness degree of the projectiles’ impact points to the target, is an important performance metric in the EMRG exterior ballistic performance assessment. To provide a systematic solution for the measure of firing accuracy, the assessment factors are formulated in detail. Then, a general framework, including trajectory simulation, data preprocessing, parameters estimation, and hit probability calculation, is proposed to evaluate EMRG firing accuracy. Considering the trajectory simulation experiments may be time consuming, a new multicriteria optimal Latin hypercube design method is presented to maintain the balance between experiment time and sampling performance. Finally, firing accuracy assessment of 16-kg projectiles is performed using the designed framework and proposed experimental design method. The result reveals that the circular error probability is about 5 km under current defined scenarios, which means the initial disturbances may have great impact on the firing accuracy of projectiles without guidance and control units.
