摘要
基于几何绕射理论研究了圆锥体以及圆柱体上精确的绕射线寻迹方程 ,所得公式在射线寻迹上适用于远场与近场 ,比目前文献提及的方法更精确 .数值计算结果在远场情况下与文献结果吻合 。
Based on GTD, this paper presents accurate tracing equations for the diffraction ray on the cone and cylinder which are suitable for both the far field and the near field and more accurate than those in the literature published in recent years. Numerical results agree with those in the reference in the case of the far field. By this method satisfactory results are obtained in engineering computation.
