The problem of primary importance in the study of reflection or refraction seismograms is to recognize effective impulse on the records. If a single seismometer were utilized to determine movement of the ground following a shot, it would generally be quite difficult to distinguish with surety the effective waves from spurious energies recorded on the seismogram. In seismic prospecting, the visual identification of effective waves is made possible by the method of simultaneously recording the motion of ground by using as many as 20 to 60 separate detecting seismometers on the same record. The alignment of the impulsive forms across the seismogram is usually referred to as "line-up" or "cophasal-axis" of seismic signal. By using the general probability distribution function of Rayleigh and assuming that seismic waves, are of the Ricker wavelet form, the problem of determining how far random noise statistically limits the detection of seismic cophasal axis in seismogram is studied. The idea that determination of signals of minimum detectable signal—threshold and the dependence of signal threshold on some kinds of parameters was discussed in detail. It may be of interest to mention that signal threshold may be controlled by such interference systems as multiple seismometers, pattern shooting, mixing circuits and magnetic head combination method in reproduction.
