飞翼布局双站雷达散射截面仿真与分析
|
摘要
针对飞翼布局广泛应用于隐身飞行器和双站探测日益成为反隐身的重要手段,总结飞翼布局的双站散射规律及双站探测策略;采用多层快速多极子算法,仿真计算3种典型飞翼布局的双站雷达散射截面;仿真计算结果表明,平行原则仍然适用于双站雷达散射截面减缩;从反隐身角度考虑,接收雷达应布置在2倍机翼前缘/机身侧棱后掠角和180°的双站角位置,以捕捉目标较强的前向散射波峰;对抗水平极化的雷达,宜采用布局2和布局3形式的飞翼布局,对抗垂直极化的雷达,宜采用布局1和布局3形式的飞翼布局。
It is important to summarize the bistatic RCS behavior and detecting strategy of flying wings with the flying wings widely used in stealth aircrafts and bistatic detecting has been anti-stealth measure.The bistatic RCS of three typical flying wings are numerically simulated with multilevel fast multipole algorithm(MLFMA).The numerical simulation results demonstrate the parallelism principle is also applicable to bistatic RCS reduction.The radar receiver should be located at twice the angle of wing leading edge or fuselage edge or at the bistatic angle of 180°in order to capture the strong forward-scattering RCS peak from anti-stealth point of view.It is appropriate to use configuration 2 and configuration 3 to confront the radar with horizontal polarization,and configuration 1 and configuration 3 are suitable to confront the radar with vertical polarization.
