舰载声纳同频干扰目标最大掩蔽距离建模与仿真

以声纳方程为基础模型,根据声纳直达波对邻近同型号声纳的干扰,得出了干扰方程。计算了在舰艇编队搜潜中,舰载声纳的探测距离和舰艇间同频干扰能够掩盖目标的最大干扰掩蔽距离,并简要地提出了降低同频干扰的方法,对编队战术决策提供技术上的依据,对提高编队的搜潜效率和声纳的作战效能具有指导意义。

The Modeling and Simulation of Maximum In-line Jamming Range Between Shipborne Sonar

Through the basic model of sonar equation,based on the directive interference between vessels in the anti-submarine formation,through the interference equation,this paper establishes the relation between the max Line-Jamming rang of active sonar and the detecting range,several solvable methods are proposed in the end.The result can offer technology supports for decision-making of tactical officer,which means a lot to improve the operational efficiency of sonar and anti-submarine vessel formation.
