摘要
在国内外有关实测数据及研究现状的基础上,对尾流环境下的混响进行了模拟,研究了尾流中气泡尺寸分布函数和尾流散射系数等参数的计算方法,建立了舰船尾流回波的声学模型。分别对鱼雷工作在尾流区和非尾流区的回波信号进行仿真实验和比较,仿真结果表明鱼雷工作在尾流区和非尾流区的回波信号是明显不同的,这为尾流自导鱼雷探测舰船的尾流从而进行目标的跟踪和打击提供了依据及研究基础。
The reverberation in the environment of ship wakes on the basis of measured data and research status. The algorithm of some parameters such as size distribution function of air void and wake scattering coefficient is presented. Acoustic model of ship wake echo wave form is established in this paper. The echo signal of torpedo which works in the ship wake region and nonwake region is simulated, and the distinction between the two different regions is showed. It makes the basement of foundation for wake homing torpedo detection wakes of ship for tracking and attacking the target.
