| 摘 要： | 建立以某舰船为参照的艏向与正横向的近似二维模型，基于二维时域有限差分法计算舰船的艏向与正横向在不同频率入射波情况下的雷达散射截面，并根据计算结果对某舰船的雷达隐身特性进行分析．此方法能用于分析现有舰船的电磁散射特性，也能用来预估和优化未来武器系统对目标的电磁散射特性要求，为日后舰船RCS预估计提供依据．

| Abstract: | A naval vessel＇s approximate ship- bow and athwartship 2- D models were modeled By the 2- D FDTD （finite difference time domain） method, a naval vessel＇s ship- bow and athwartship RCS under the incident wave with different frequencies were calculated. Then based on the results, the characteristics of radar stealth of a naval vessel were analyzed The calculation for RCS can not only be used to analyze existing ship＇s electromagnetic scattering characteristic, but also he applied to forecast and optimize future weapon system＇s electromagnetic scattering characteristic requirement for target. The stealthy characters of the naval vessels were analyzed here for farther research. |
