针对水面舰艇编队尾后方向的潜艇威胁,研究反潜直升机使用吊放声纳搜潜中的警戒扇面、兵力需求、参数决策等问题。通过分析锯齿形法特点、吊放声纳搜潜过程,建立了多机舰艇编队尾后搜潜的警戒扇面定量计算模型。研究了齿形法相邻探测点间距系数、搜索速度等制约因素,探索了吊放声纳作用距离与潜艇航速的定量关系,给出了已探测区等效圆半径的计算方法。仿真计算了舰艇编队尾后搜潜中实际对潜警戒扇面、最优间距系数、不同任务要求下的兵力需求。结果表明:配置2架直升机于舰艇编队尾后15海里处,可建立80.9°的对潜警戒扇面;齿形法最佳间距系数介于1.1~1.3之间。
Aiming at the threat of submarine in the rear of the surface ship formation, this paper studies the search of anti-submarine helicopters using snail sonar to search for potential warning sectors, troop demands and parameter decisions. By analyzing the characteristics of sawtooth method and sonar search and submarine search and submarine search, a quantitative calculation model of warning foraging submarine after multi-machine warship formation is established. The factors such as the spacing between adjacent detection points of tooth profile method and the search speed were studied. The quantitative relationship between the distance of sonar and the submarine was explored. The calculation method of the equivalent circle radius of the detected region was given. The actual demand for submarine warning fans, the optimal spacing coefficient and the requirements of troops under different missions are calculated by simulation. The results show that the optimal distance between two helicopters at 15 nautical miles behind the tail of the ship formation is 80.9 °, and the best pitch coefficient of the tooth profile is between 1.1 and 1.3.
