【摘要】 对波动方程叠前深度偏移的成像条件和平滑算子进行了概述,推导了用平滑算子对成像条件进行平滑的公式,给出了同一平滑函数在不同平滑参数控制下以及不同平滑函数在相同平滑参数控制下的成像结果。模型试算结果表明:在合适的平滑参数控制下,平滑后的成像结果得到了明显改善;在相同的平滑参数控制下,Gaussian窗平滑算子平滑后得到的成像结果要好。更多还原

【Abstract】 The imaging condition and smoothing operator of wave equation prestack depth migration were introduced.The formula used smoothing operator to smooth imaging conditon was derived.The results of the same smoothing function with different smoothing parameters and different smoothing functions with the same smoothing parameter were given.The model test results show that the images are improved when the smoothing parameter is appropriate.With the same smoothing parameter,Gaussian smoothing operator can get relatively good imaging result.更多还原
