Abstract:

The article presents the results of experimental studies of noise immunity of seismic detection, a method of signal processing to improve the signaling reliability of seismic detectors.

The article describes the method of seismic signals detection using Bayesian energy detector. A representative database of seismic signals and noise realizations was created for the study. All signals were pre-centered. The assumption of stationarity and ergodicity of the studied signals is put forward. The generalized exponential distribution is taken as a basis of the model. It is shown that the probability of correct detection can be more than 0.99 with a false alarm value of 0.002. The average risk value of the system is 0.009.
