| 摘 要： | 主要根据误差能量和频谱特征，分析地震资料处理中最小平方反滤波白噪化后反滤波因子、滤波结果和地震子波的变化。指出选择适当小的白噪因子λ，可使反滤波因子稳定，提高滤波效果，有效地提高分辨率。

| Abstract: | This paper discusses in detail how to obtain the inverse wavelet by using least squares, why the effect of conventional inverse filtering is not so positive, and also analyses the inverse filtering effect after noise whitening from error energy, frequency characteristics, the information difference between whitened and nonwhitened noises, and other aspects. |

| Keywords: | Seismic data processing least squares inverse filtering noise whitening seismic wavelet |
