摘要
声呐作用距离是评估和预报声呐性能的重要指标。由于浅海环境复杂,确定主动声呐的工作深度,使探测距离达到最远,是充分发挥声呐性能的关键。通过射线声学理论进行声场仿真,利用声呐方程建立声呐探测距离模型,根据传播损失与声呐优质因子的关系得到不同声呐工作深度对应的探测距离。结果表明,在不同的声速剖面下,声呐在海底的工作深度不同,其对目标的探测距离会有很大不同。找到最佳的探测距离对应的工作深度,能够保障声呐的最优探测能力。
The sonar operating distance is an important indicator for evaluating and predicting sonar performance.Due to the complex environment in shallow sea,determining the working depth of active sonar to achieve the farthest detection distance is the key to fully utilizing sonar performance.Firstly,the acoustic field is simulated by ray acoustic theory,and the sonar detection distance model is established by using sonar equation.According to the relationship between propagation loss and sonar quality factor,the detection distances corresponding to different sonar working depths are obtained.The results indicate that under different sound velocity profiles,the detection distance of the sonar will vary greatly with the varying working depth of the sonar.Finding the optimal detection distance corresponding to the working depth can ensure the optimal detection capability of the sonar.
