| 摘 要： | 针对F117A隐身飞机通过独特的几何外形设计来实现隐身的特点,利用网络并行FDTD方法,在网络并行计算系统平台上,计算和分析了其电磁散射特性,包括低频散射特性、高频散射特性、俯仰特性、双基地特性和时域波形特性,同时还给出与微波暗室实测结果的比较,验证了计算结果的正确性。通过计算获得了一些有价值的数据和结论,为反隐身雷达设计提供了理论依据。

| Abstract: | According to the stealth character of F117A stealth fighter by its unique geometric shape,the EM scattering characteristics of F117A stealth fighter are computed and analyzed with the network parallel FDTD method on network parallel computing system,such as the low-frequency,the high-frequency,the pitching,the bistatic,and the waveform in time domain.At the same time,compared with the measured result,the correctness of the computed result is proved.Some valuable data and conclusions are obtained,and can be provided as the theoretical bases for the design of anti-stealth radar systems. |
