我们比较和对比反投影图像的定性性质 在使用共炮检距数据时在地震成像中获得的 而不是使用普通的中点数据。我们的结果显示 使用公共中点数据获得的图像包含伪影 它们不具有公共偏移量数据。尽管有 人们仍然想要使用公共中点数据的情况, 这一结果指出了一个缺点,应该记住,当 解读这些图像。
We compare and contrast the qualitative nature of backprojected images obtained in seismic imaging when common offset data are used versus when common midpoint data are used. Our results show that the image obtained using common midpoint data contains artifacts which are not present with common offset data. Although there are situations where one would still want to use common midpoint data, this result points out a shortcoming that should be kept in mind when interpreting the images.
