文章对标准抛物线方程(SPE)的分裂步傅里叶变换(SSFT)方法进行了详细的分析,引入一种适合SPE的不规则地形建模方式,利用SSFT算法计算自由空间与不规则地形的电波传播问题,与经典理论计算所得的结果相当吻合。%Standard parabolic equation (SPE) with Slip-step Fourier Transform (SSFT) method and SPE modelling of radio propagation over irregular terrain are elaborated. To work out radio propagation in vac uum and radio propagation over irregular terrain with SSFT method is identical to the results available by the classical method.
