DETECTING SEISMIC SIGNAL BY SIGN-BIT

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.
