摘要

F-117夜鹰隐形战斗机是世界上第一架真正的“隐形”飞机，具有低雷达横截面(RCS)。改变RCS的两个最重要的参数，如雷达收发器的频率和俯仰角，最好的输出被记录为结果。利用COMSOL Multiphysics软件建立了F-117的虚拟腔室，并将其CAD模型应用于其中。本文采用双基地RCS计算方法进行仿真。结果清楚地表明，RCS在S波段和X波段波段的较高频率范围内获得效果较好，在某些特定的面向角下，结果具有较高的可探测性。

Analytical Study of Bi-Static Radar Cross Section with a Comparison at S Band and X Band of F-117 Nighthawk Stealth Aircraft

F-117 Nighthawk Stealth Fighter Jet is the world’s first true ‘Stealth’ aircraft that has low Radar Cross Section (RCS). Varying two of the most important parameters of RCS such as frequency of the radar transceiver and aspect angle, the best outputs are recorded as the results. Using COMSOL Multiphysics software a virtual chamber has been created and the CAD model of F-117 is applied in it. In this paper, the bistatic RCS calculation method is done for simulation. The results clearly depicted that RCS can be obtained better at higher frequency of S band and X band wave range and at some specific aspect angles the results exhibit higher detectability.
