摘　　要：阐述了三维抛物方程(3DPE)方法的基本原理及数值实现方法,并用3DPE计算了雷达波在平地面上传播的干涉损耗和单刃锋障碍绕射损耗,与经典理论计算所得的结果相当吻合。The basic principle of three dimensional parabolic equation (3DPE) and the way of numerical implementation are expatiated. The interference loss of radar wave propagation on the flat earth and the diffraction loss through the knife-edge are evaluated by the 3DPE method. Comparing with the results available by the classical method, they show excellent agreement.
