针对鱼雷一次转角射击效果在线评估及射击诸元实时优化计算的需要,文中全面考虑影响鱼雷一次转角射击效果的多种误差因素,基于误差折算思想提出了一种鱼雷一次转角射击命中/发现概率的解析计算模型。该模型用单积分描述,同时考虑了与鱼雷射击相关的各种误差因素,与已有模型相比,可显著降低计算量。大量态势仿真结果表明,文中解析计算模型结果与统计计算结果相吻合,说明了新模型在工程应用上的可行性。

For the needs of online evaluation of torpedo one-time turning-angle shooting and real-time optimization calculation of shooting elements,a new analytical calculation model of the hitting/finding probability of torpedo one-time turning-angle shooting is proposed based on the idea of error conversion.The model is described by single integral,and all kinds of error factors related to torpedo shooting are considered.Compared with the existing model,the proposed model can significantly reduce calculation amount.A large number of situation simulations show that the results from the analytical calculation model is in good agreement with the statistical calculation results,which suggests the feasibility of the proposed model for engineering application.
