舰机协同下多基地声纳阵应召搜潜效能研究

针对传统单基地声纳搜潜难以满足反潜作战要求的问题,提出了一种拖曳声纳与反潜直升机布放浮标阵联合起来形成多基地声纳搜潜的方法。结合舰机实际运动特点,建立舰艇运动模型与直升机布放圆形、方形、三角形被动浮标阵模型。采用Monte Carlo方法,对搜潜概率进行仿真,比较多基地与非多基地声纳的搜潜概率,并分析不同的初始条件对搜潜概率的影响。仿真结果表明,多基地声纳搜潜概率高于非多基地声纳,圆形多基地阵搜潜效能相对最佳,三种阵型的搜潜概率随着初始距离、初始位置分布、航速均值的增大而减小,并能针对不同搜潜要求与实际作战条件选择合适的布放半径和被动浮标布放个数。提出的方法适用于一定距离范围内的应召搜潜,对反潜作战具有一定的军事意义。

Research on the Performance of Multi-Base Sonar Arrays Under the Condition of on-Called Anti-Submarine and Warship-Helicopter Cooperation

Aiming at the problem that it is difficult for the traditional single-base sonar searching to meet the requirements of anti-submarine operations,the paper proposed a multi-base sonar searching method combining towed sonar with anti-submarine helicopter buoy array.Firstly,the ship motion model and the helicopter deployed circular,square,triangular passive buoy array model were established according to the actual movement characteristics of the warship and aircraft.Then,Monte Carlo method was used to simulate the searching probability of multistatic sonar and non-multistatic sonar,and the influence of different initial conditions on the searching probability was analyzed.The simulation results show that the searching probability of multistatic sonar is higher than that of non-multistatic sonar,and the searching efficiency of circular multistatic array is relatively optimum.The searching probability of three types of array decreases with the increase of initial distance,initial position distribution and average speed,and the suitable deployment radius and passive buoy number can be selected according to different searching requirements and actual combat conditions.The proposed method can be applied to search submarine in a certain range and has certain military significance for anti-submarine operations.
