摘要
本文应用快速汉克尔变换（FHT）计算索末菲尔德积分．它通过输入函数与滤波系数在有限滤波长度下卷积求和快速准确地求得积分值，避免了贝塞尔函数计算和数值积分的繁琐运算，大大提高了计算效率和计算精度．
Fast Hankel transform is applied to calculate Sommerfeld integral in this paper.It attains the value of integral rapidly and accurately by the convolution of input function with filter coefficients under the finite length of the filter and avoids the tedious numerical integration and computation of Bessel function,so the com putational efficiency and accuracy are improved greatly.
