| 摘 要： | 利用统计假设原理及地震信号瞬时相位的相关特性,计算了叠加速度谱。理论模型的试算和实际资料的处理结果表明:与常规速度分析方法相比,该方法具有较高的时间分辨率和速度分辨率,而且抗噪性非常好。该方法不仅不受时窗边界奇异性的影响,还可以有效地避免边缘效应,反映更多反射波信息。该方法对于层速度的精确计算很关键,同时也表明了统计方法用在多道信号估计上是有效的。

| Abstract: | In this paper, we calculate stack velocity spectrum using instantaneous phase correlation characteristic of seismic signal and statistical hypothetical test principle in probability method. We conduct test and calculation using synthetic and real data and compare with conventional velocity spectrum. The results showed that the method has higher resolution in velocity and in time and has better anti-noise property compared with conventional methods. This method, which does not suffer from time-window boundar... |
