中文摘要 | 目標物之雷達散射截面積(RCS)是表示雷達目標對於照射電磁波散射能力的一個物理量,為了得到目標物雷射散射截面積的方式大概可分為兩種,即實體或縮尺模型量測及模擬計算。本文係針對模擬計算所需之3D模型表面網格,進行多重材質網格產生及邊緣自動尋找與標定之技術開發,期能提供RAVIS(為一種雷達截面積的模擬計算程式)進行多重材料模擬計算所需之網格模型系統。為了簡化使用程序及便利性,亦結合視窗化介面,將所開發之各項分系統程式整合為一完整的3D模型網格產生系統,可有效地提昇工作效率、彈性化組合網格模型及縮短複雜外型之網格產生時程。 |
英文摘要 | Radar cross section (RCS) is a unique physical quantity of a target used to define its scattering capability of electromagnetic wave emitted from radar. Methods of estimating a target's RCS are usually divided into two categories, namely the direct measurement of scattering electromagnetic wave from full scale or scaled down target model, and the numerical simulation. In the present work we develop a numberical simulation technique that can automatically generate multiple material cells and edge-finding-and-mark needed in 3D RCS surface modeling of a target composed of multiple materials. We can thus provide a popular RCS simulation code (called RAVIS) with the above cell model system to computer RCS of that target. In order to simplify the simulation procedure and to provide greater convenience, we integrate user-friendly interface with PC's windows system. All subsystems developed are incorporated into s single and powerful 3D model cell generation package to increase working efficiency. The present work not only shows great flexibility in combining separated surface components into a final cell model, but also shows large saving of time in cell generation for target of complicated configuration. |
