METHOD FOR PROVIDING REQUIRED PROBABILITY OF FALSE TRIGGERING OF SEISMIC SIGNAL CLASSIFICATION DEVICE Russian patent published in 2019 - IPC G01V1/16 G08B13/16 

FIELD: physics.

SUBSTANCE: invention relates to technical means of detecting and classifying seismic signals and can be used to protect areas of terrain and approaches to objects, in reconnaissance and signalling systems and in control devices for blasting engineering ammunition. Disclosed is a method of providing required probability of false triggering device classification of seismic signals. At high requirements to probability of false triggering of seismic facilities, providing classification and recognition of sources of seismic vibrations, for example, to seismic sensors of target, used for actuation of engineering ammunition, determining probability of false triggering is not provided experimentally and involves establishment of distribution law and its parameters for the controlled information feature, which is usually the maximum values of pulse signals. Processing of results of field measurements of seismic background, its maximum values of envelope in time windows, has shown validity of hypothesis on conformity of distribution of this information feature to distribution law of maxima, which allows in field conditions to determine threshold level, providing the required probability of false triggering by parameters of a specific seismic background when classifying sources of seismic signals, based on analysis of dynamics of signal change in time.

EFFECT: technical result is providing the required probability of false triggering device classification of seismic signals, while maintaining high probability of correct recognition of signals.
