| 摘 要： | 提出了一种基于FDTD方法的双站RCS计算方法即瞬态外推时谐场的离散傅立叶变换方法。此法不仅为工程应用提供方便,而且节约了计算时间、提高了计算的精度;文中针对FDTD复杂目标建模给出了一种基于3ds max的建模方法,这种建模方法可以对复杂目标实现快速、准确、可视化建模。运用上述方法,计算了典型目标和复杂目标双站RCS。算例结果表明,该方法是可行的。

| Abstract: | A novel method for computing object bistatic RCS based on FDTD method is dealt with,in which,the extrapolation result of steady state can be obtained from the FDTD computation of transient state by discrete Fourier transform.This method is not only convenient in engineering application,but also saves the computing time,and improves its computational precision.A novel technique based on 3DS Max for FDTD modeling is presented and applied to complex-object modeling in this paper,too.The visual FDTD modeling ca... |
