The purpose of the detection processes, which will be presented below, is to investigate the differences between signals and noise, in order to improve the detection capability. Depending on the type of seismic signals, different detection methods can be used.
\nCommonly used method of filtering the observed data is based on information about the ratio of noise and signal energy. In addition, the spectral composition of seismic signals often differs from the spectral composition of noise, and therefore in this case, the comparison of spectral components is proposed as a possible method to obtain optimal filtering. Noise suppression filters can be useful in cases where only the signal characteristics are known. It is possible to distinguish the type of noise suppression filter, when the prehistory of the process, free of signals, noise is expected, and removes the predicted noise in the fragments where the appearance of signals is expected. They require a high level of noise stationary. Even in this case, error prediction filters are usually less effective than conventional bandpass filters. It should be noted that the seismic background noise produced by the total oscillations of the Earth establishes a natural limitation to what can be detected by seismic equipment.
\nSeismoacoustic monitoring is a mode observation to detect and identify signals on the background of seismic noise in the seismoacoustic frequency range. The purpose of the processes of detection and evaluation of a seismic signal on the background of microseismic noise is to investigate the differences between signals and noise, in order to improve the detection capability. Depending on the type of seismic signals, different detection methods can be used. The procedure is based on the assessment of the ratio of short-term signal power to long-term signal power has long been used. If the ratio exceeds the set level, then a decision is made that the detection occurred. This algorithm is used when deciding on the presence of a signal and a rough estimate of the moment of its entry.
