符号位地震信号处理,具有存贮少、运算快的优点,在地震资料处理中具有广阔的应用前景。本文从理论上讨论了符号位地震信号检测问题和符号位地层参数检测问题,根据参与处理的道数多少和时窗大小,给出了不同的检测方法,这些方法便于实际应用。

Detecting seismic signal by sign-bit is one of the important problems in sign-bit processing. It will be discussed in this paper. First, we use the Binomial and normal distribution test methods to solve the seismic signal detection at a time sample point. Then, when we discuss the seismic signal detection in a time window, we present the chi-square distribution tets method according to generalized likelihood ratio test theory. Finally, the stratigraphic parameters detection problem will be discussed. The tsratigraphic parameters can be detected by scanning parameters such as the 2-D dip and velocity for layered medium with arbitrary dip.
