| 摘 要： | 利用时域一致性绕射理论和物理光学的方法来分析含有多个圆形曲边缘障碍物的多重绕射模型.由于该方法利用一组简单的递推关系来代替一致性绕射理论中复杂的斜率绕射项,从而提供了一种简化的基于时域一致性绕射理论的多重绕射分析方法.数值结果表明,这种改进的基于时域一致性绕射理论的分析方法不仅能够用来准确地分析多重圆形曲边缘障碍物绕射模型,而且还能够明显减少运算时间.

| Abstract: | A time domain (TD) solution based on uniform theory of diffraction physical optics (UTD-PO) is presen
ted to analyze the multiple cylinder diffraction. Since the solution utilizes a simple recursion relation, the complicated slope
diffraction in UTD is avoided, which provides an improved TD-UTD solution for multiple diffraction. The numerical results
show that the improved TD-UTD solution can not only be applied to analyze the multiple-cylinder diffraction for UWB signals,
but also significantly reduce the computational time. |
