中文摘要 | 本文主旨在利用驗證過的雷達截面積計算分析軟體RAVIS,針對不同開口外形和長度之進氣道結構,做數值實驗,深入了解進氣道開口幾何形狀和長度對飛機之進氣道雷達截面積的影響。並進一步分析典型戰機進氣道的雷達截面積。 |
英文摘要 | The radar cross section (RCS) analysis of Inlets with arbitrary cross sections and different length is carried out by the RCS code RAVIS. RAVIS used a hybrid high-frequency technique of the Shooting and Bouncing Ray (SBR) method, the Physical Optics (PO) and Physical Theory of Diffraction (PTD). A dense grid of rays is launched into the inlets through the opening. The rays bounce from the inlet wall based on the laws of geometrical optics and eventually exit the inlet via the aperture. RCS results for a tilted-rectangular cross section show significant RCS reduction. |
