Influence of Battlefield Currents on Operational Effectiveness of Tube-Launched Torpedo Anti-Submarine

摘要: 海流的存在对反潜作战的声呐状态、鱼雷和目标等均有一定影响, 严重时甚至会影响作战结果。文中以水面舰反潜为例, 开展了多种作战想定的反潜全流程仿真, 研究海流对反潜作战效能影响。通过构建海流、声呐误差、鱼雷运动与自导检测误差等数学模型, 设定多种想定态势并结合仿真软件, 分析了不同海流流向下的管装鱼雷反潜作战效能。仿真结果表明, 不同攻击阵位下反潜作战中海流流向对鱼雷命中概率具有不同程度的影响。当海流与鱼雷设定主航向夹角在0°~90°之间时, 鱼雷的命中概率相较于无海流时提升较大, 而当海流与鱼雷航向的夹角在−180°~0°之间时, 鱼雷命中概率较无海流的情况下有所降低。通过获取作战海域的海流强度及走向可为精细化预估管装鱼雷反潜作战能力、优化管装鱼雷反潜射击参数提供支撑。Abstract: The existence of ocean currents has a certain impact on the sonar state, torpedoes, and targets during anti-submarine operation. In severe cases, it may even affect the result of the operation. The anti-submarine operation of a surface ship was taken as an example, and a full-process simulation of the anti-submarine combat under various scenarios was carried out to study the influence of ocean currents on the operational effectiveness of anti-submarine. By constructing mathematical models of ocean current, sonar error, torpedo motion, and homing detection error, setting up various scenarios, and employing simulation software, the operation effectiveness of tube-launched anti-submarine torpedoes under different ocean current directions was analyzed. The simulation results show that the current direction during anti-submarine operation in different attack positions has different degrees of influence on the hit probability of the torpedo. When the main heading angle between the current and the torpedo is set between 0° and 90°, the hit probability of the torpedo is greatly improved compared with that in the case of no current. However, when the angle between the current and the torpedo heading is between −180° and 0°, the hit probability of the torpedo is lower than that in the case of no current. Obtaining the current intensity and direction in the operation area can provide support for finely predicting the operation capability of the tube-launched anti-submarine torpedo and optimizing the tube-launched anti-submarine shooting parameters.
