| 摘 要： | 对标准抛物线方程进行分裂步傅里叶变换(SSFT)算法的求解,并应用到自由空间的电波传播问题中.较有限差分法(FD)算法求解标准抛物线方程,该方法更适合于大尺度电波传播问题,且求解速度快,稳定性好.

| Abstract: | Slip-step Fourier transform(SSFT) method was used for solving parabolic equatcon(PE).It was applied in radio propagation in vacuum.The algorithm was more fit for handling large scale problem of radio propagation than solving standard PE with finite difference(FD).The algorithm improves the calculating speed and stability. |
