摘要
本文研究常见、典型的水中目标体外形的回声特性是目标回声特性研究的基础内容。采用基于Kirchhoff近似的平面元方法和几何建模软件相结合的数值方法计算研究了三种典型外形的收发合置的目标强度。通过对计算结果的对比分析,归纳得到了一些高频回声规律。
Researches on echo characteristics of submerged typical configurations are the groundwork of target echo characteristics. The monostatic target strength of three typical configurations has been calculated by numerical computation method, which combines planar method rooting from Kirchhoffapproximation and geometric modeling software. Some high-frequency echo laws have been summed up by the comparison analysis of the results.
