| 摘 要： | 通过对声呐方程中参数随机性的分析，采用理论推导的方法得出传播损失为球面衰减和平滑平均场时．声呐作用距离的概率密度函数，并求得均值和方差。同时，采用蒙特卡洛方法进行模拟，得出的作用距离概率统计直方图与推导结果吻合较好，证明了推导结果的可信性。

| Abstract: | The stochastic of sonar equation parameters is analyzed,and the probability density function of sonar detect range in spherical attenuation or smooth-averaged field is deduced though theoretical derivation,then the mean and variance are obtained.At the same time,the simulation using Monte Carlo method shows that the obtained sonar detect range histogram of probability and statistics can agree well with the derivation,and the credibility of the results derived is proved. |
