摘要: 鱼雷海上试验结果评定时, 鱼雷过目标情况及非触发引信动作功能等的评定需要高精度、高采样频率的鱼雷弹道数据, 但单纯依靠鱼雷内、外测弹道数据难以满足评定要求, 同时尚无适用的弹道融合方法。针对此, 文中提出一种基于时差加权法的鱼雷内、外测弹道数据融合处理方法, 结合了鱼雷内、外测弹道的优点, 融合得到的鱼雷弹道具有高精度且高采样频率的优点, 完全满足鱼雷过目标情况、非触发引信动作功能等评定的弹道要求, 在鱼雷试验领域具有实用价值。Abstract: The torpedo trajectory data with high precision and high sampling frequency are needed for evaluating torpedo over-target situation and non-triggered fuze action function when torpedo sea trial results are evaluated. However, it is difficult to meet the evaluation requirements only by means of internal and external torpedo trajectory measurement data, and there is no applicable trajectory fusion method. In view of this, a fusion processing method of internal and external torpedo trajectories’ data based on the time difference weighting method was proposed, which combined the advantages of internal and external torpedo trajectories. The torpedo trajectory obtained by fusion has the advantages of high precision and high sampling frequency, which can fully meet the trajectory requirements for evaluating torpedo over-target situation and non-triggered fuze action function, and it has practical value in the torpedo trial field.
