| 摘 要： | 本文在采用计算机图形学对某犁隐身飞机进行电磁建模的基础上,利用FDTD方法和电磁计算软件Microwave Studio对飞机在低频段(短波和米波波段)的RCS进行了计算,包括不同极化和不同入射角度条件下的单站和双站RCS.比较两种方法的计算结果证明在低频段该飞机有可能出现较强的谐振频率点,因而利用低频段雷达有可能实现对隐身飞机等低可探测目标的检测和跟踪. |

| Abstract: | Using computational graph to construct the electromagnetic model of some stealth plane,FDTD and electromagnetic simulation software(Microwave Studio) are adopted to calculate the RCS of this plane in HF and VHF band.The monostatic and bistatic RCS are considered under different polarization styles and different incident angle.The numerical results demonstrate that this stealth plane will express strong resonant frequency point,and low frequency radar has the potential to detect and track stealth target. |
| Keywords: | FDTD Radar cross section(RCS) Stealth target |
