应用迭代方法及FFT程序可以有效地由频域反射数据来重建分层介质的特性剖面,剖面的重建可以在指定区段,无须从分界面开始。计算表明,这一方法对噪声干扰有较好的稳定性。并且,在介质剖面含有不连续点时仍能相当好地实现重建。
The iterative method and the FFT program can effectively reconstruct the characteristic profile of the layered media from the reflection data in the frequency domain. The reconstruction of the profile can be in the designated segment without starting from the interface. The calculation shows that this method has a good stability against noise interference. And reconstruction can still be done quite well when the media profile contains discontinuities.
