摘　　要：针对反潜直升机吊放声呐搜潜效能评估过程中把探测范围等效成半径为定值圆的问题,为了提高效能评估的逼真度,文中以吊放声呐扩展螺旋阵数学模型为基础,建立了吊放声呐探测距离模型。依靠射线声学理论模型,以深海负梯度声速为例,通过BELLHOP仿真得出了吊放声呐探测距离随温深曲线变化的关系,发现吊放声呐的探测距离在真实情况下是随着声速梯度的变化而改变的。同时,针对潜艇在逃逸过程中沿直线航行的问题,建立了潜艇规避模型,得出了潜艇规避仿真图。将探测范围等效成半径为定值圆的模型称为第1模型;在第1模型的基础上引入吊放声呐探测距离随温深曲线变化模型,称为第2模型;在第2模型的基础上加入潜艇规避模型,称为第3模型。使用蒙特卡洛方法对3种模型分别仿真5 000次,结果表明,加入射线声学理论探测距离模型和潜艇规避模型后,搜潜效率大大降低。文中方法对提高吊放声呐阵型搜索效能评估逼真度具有一定的军事意义和参考价值。Aiming at the problem that the detection range is equivalent to a circle with fixed radius in the evaluation process of submarine search effectiveness of anti-submarine helicopter dipping sonar,this paper establishes a detection range model of sonar based on the extension spiral array mathematical model of sonar in order to improve the fidelity of effectiveness evaluation.Based on the ray acoustics theory model,the negative-gradient acoustic velocity in deep sea is taken for example to obtain the relationship between the detection range of the dipping sonar and the temperature as well as the depth curve via BELLHOP simulation,and it is found that dipping sonar detection range in real case is subject to change with the velocity gradient.Furthermore,aiming at the problem of submarine navigation along a straight line in escape process,this paper establishes a submarine elusion model,and obtains the simulation diagram of the submarine elusion.The model of the detection range equivalent to a fixed circle with radius is named as the first model.The first model with the addition of the detection range model is called the second model,and the second model with the addition of the submarine elusion model is called the third model.The Monte Carlo method is used to simulate the three models for 5000 times,respectively.The results show that the detection range model with ray acoustics theory and the submarine elusion model greatly reduce the efficiency of submarine searching.Through simulation analysis,the goal of improving the fidelity of the effectiveness evaluation of sonar array search is achieved.
