飞行器隐身技术之一是阻抗加载。本文研究充电大尺寸(ka=10)任意截面多表面阻抗加载凸导体柱的电磁散射。问题的反应积分方程是采用组合Fock理论和矩量法的混合方法建立,并由Leontovich阻抗边界条件来求解的。对一个多表面阻抗加载圆柱体的混合法的数值分析表明,利用多表面阻抗加载,可实现较大角范围内后向雷达散射截面(RCS)的减缩,并同时产生后向散射相位的强烈跃变,从而获得大的角闪烁线偏差,这是一种新的隐蔽技术措施。
One of the aircraft stealth technologies is impedance loading. In this paper, we study the electromagnetic scattering of charged large conductor (k = 10) arbitrary surface multi-surface impedance loaded convex conductor columns. The reaction integral equation of the problem is established by the hybrid method of combinatorial Fock theory and moment method and solved by Leontovich impedance boundary conditions. The numerical analysis of a hybrid method for a multi-surface-impedance-loaded cylinder shows that with multi-surface impedance loading, the RCS reduction in the larger angular range can be achieved with a strong jump in the backscattering phase , Resulting in a large angular flash line deviation, which is a new concealed technical measures.
