Abstract
Abstract. Seismoacoustic monitoring of explosive fields is a key tool for remote exploration based on multiple regime observations in specific (infrasonic and acoustic) frequency ranges. Monitoring modes and spectral parameters of objects depend on the unique characteristics of the research targets. The reliability of explosive signal classification is improved by integrating information technologies into the monitoring process. The aim of the work is to develop and justify an improved method of seismoacoustic monitoring that ensures high reliability of explosive signal classification. The key idea of the method is to transition from complex time signals to their representation in the vector space of informative parameters. The monitoring process boils down to evaluating these parameters of parametric mathematical models of separate and nonseparate signals of the explosion field, the superposition of which forms the explosion field itself. The set of these parameters forms a vector in $n$-dimensional Euclidean space, which uniquely characterizes the signal. Thus, signal classification boils down to the classification of these vectors.
To achieve this goal, a parametric mathematical model of an indivisible signal has been developed that takes into account the transfer function of the medium, interference parameters, and natural noise background. Optimized procedures for processing observed data have been proposed, which are based on a priori statistics of the random interference process and take into account the instability of parameters, which allows the influence of interference to be minimized. An approach has also been formulated and tested, in which the classification of explosive signals (to determine the type of explosion source) is performed by classifying the corresponding vectors in n-dimensional Euclidean space. The results of the work can be used to determine the location and type of enemy weapons in remote reconnaissance systems.
