| 摘 要： | 采用Monte-Carlo方法捕捉浅海中声速剖面的不确定性,模拟真实海洋环境中的声速剖面,并将模拟得到的声速剖面输入波束位移射线简正波(BDRM)声场预报模型中,得到声传播损失,再对结果进行统计分析,得到声传播损失的概率分布图,并提出用传播损失期望值作为预报值,提高了声场预报的精度.最后,利用声纳优质因子(FOM)导出声纳作用距离概率分布图,为声纳作用距离的预报提供了概率的依据.

| Abstract: | The way of taking the uncertainty in this paper is imitating the sound speed profile of the ocean with the Monte Carlo simulation,and using the Beam-Displacement Ray-Mode model(BDRM) to calculate transmission loss,then getting the probability distribution histogram of transmission loss in each distance and figuring that using expectation of transmission loss as the forecasting value will improve its precision.Finally,deriving a sonar action range probability distribution histogram by using FOM and giving a ... |
