特定形状小目标的回波特性分析

Research on the echo characteristics of small target with special shape

摘要: 通过商业建模软件ANSYS对特定形状小目标进行精确几何建模,利用基于物理声学的板块元方法,对特定形状小目标的几何回波特性进行理论研究,包括目标强度和几何回波亮点结构。通过缩比模型的水池实验和数据分析,将理论预报结果和实测结果进行了比较,结果吻合较好。

Abstract: Based on the planar element method and the physical acoustic method,the geometric echo characteristics including target strength and geometric echo highlight structures of small targets with special shapes,which are modeled by commercial drawing software,are calculated.The results are tested and verified by pool experiment and data analysis.
