摘要
哈特莱变换(HT)是一种实数变换,其正、更变换相同,且具有傅里叶变换(FT)的大部分性质。利用快速哈特莱变换(FHT)进行声波方程的数值模拟,其计算速度比 FFT 要快,且效果相当。
Hartley Transform is a real number transform,and its forward transform is the same as its inverse transform.What is more,Hartley Transform shows most proper- ties of Fourier Transform.Fast Hartley Transform brings faster numerical modeling of acoustic wave equation than fast Fourier Transform does,with their effects equivalent.
