Abstract

Abstract:

In accordance with the difficulties posed by the substantial usage of computing resources for simulation methods， this study presents an analytic model that specifically examines the effectiveness of long-range torpedo anti-submarine search operations. The dispersion of target locations during patrol search and on-call search is meticulously examined， taking into consideration the tactical requirements and the detection principle in the process of long-range torpedo attack. Furthermore， the analytic model of long-range torpedo anti-submarine search effectiveness is constructed with the detection probability serving as the primary indicator. Realistic anti-submarine combat scenarios are employed to apply both the analytic model and simulation method， which results in a simulation test of the long-distance torpedo anti-submarine search. The findings of the test reveal that patrol search efficiency improves with an increase in the number and average speed of long-range torpedoes， but decreases with an increase in the mission area. On the other hand， on-call search efficiency improves with an increase in the average speed of long-range torpedoes. The calculated values derived from the model align well with the results of the simulation method.

Key words: long-range torpedo, anti-submarine warfare, effectiveness analysis, detection probability, target location dispersion

摘要：

针对模拟法占用计算资源较多的问题，构建了一种远程鱼雷反潜搜索效能评估模型。依据反潜作战的战技术需求和远程鱼雷搜索发现原理，深入分析了巡逻搜索和应召搜索下的目标位置散布，进而以发现概率作为搜潜效能指标，构建了远程鱼雷反潜搜索效能评估模型。在典型反潜作战场景下，分别运用搜潜效能评估模型和模拟法，进行远程鱼雷反潜搜索仿真试验，试验结果表明，巡逻搜潜效率随远程鱼雷数量和平均航速增加而提高，随任务区域面积增大而降低；应召搜潜效率随远程鱼雷平均航速增加而提高。该模型的计算值与仿真试验结果具有较好的一致性。
