| 摘 要： | 水下尺度目标回声特性是水声学中的一个重要研究方向。该文首先介绍了尺度目标近程回波的多亮点模型,采用板块元算法计算亮点的目标强度,同时结合面元的反射强度值和照射区域计算亮点位置,最后以一段圆柱体目标和一个简单形状的组合体目标为研究对象,进行了计算机仿真。仿真结果较好地体现了目标的回波结构,表明采用亮点模型模拟目标回波对于分析水下尺度目标的声学特性具有一定的应用价值。 |

| Abstract: | The echoes characteristics of underwater scaling targets in short range is an important research branches of acoustic subject.Firstly,the echoes highlight model of underwater targets is introduced.Secondly,the planar element method is used to calculate the highlight strength.Meanwhile,the highlight distribution is determined based on the reflection coefficient of planar element and the reflection area.In the end an infinite cylinder model and a simple submarine model are taken as the example.Numerical calcu... |
