反潜直升机吊放声纳水面舰艇编队尾后锯齿形法搜潜

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。

Antisubmarine helicopter searching stern of ship formation adopting saw-tooth method with dipping sonar

The warning sector,demand of force and parameter decisions in helicopter antisubmarine search for threat from stern of ship formation with dipping sonar are investigated.The process of antisubmarine search with dipping sonar and the features of saw-tooth method are analyzed.A quantitative model for warning sector is built for multiple helicopters antisubmarine search at stern of ship formation.The influencing factors of saw-tooth method are analyzed,such as search velocity,and the spacing coefficient of adjacent detecting points.The relationship between submarine velocity and detection range of dipping sonar is investigated.The method for calculating equivalent circle radius of the detected area is provided.The actual warning sector against submarine,the optimum spacing coefficient,and the force demand when antisubmarine helicopters search the stern of ship formation using dipping sonar are simulated.Results show that deploying 2 helicopters to 15 n miles at the stern of ship formation could cover warning sector of 80.9°,and the optimum spacing coefficient is between 1.1 and 1.3.
