Marksa, Novosibirsk, 630073, Russian Federation Abstract The paper contains the analysis of problems that appear when algorithms for data processing in passive seismic location are developed. This technology is useful for guard systems based on the seismic signal processing principle. The paper describes the seismic signals statistical optimal processing methods for detection and classificatioon. The advantages of spectral criterions based on power spectral density and smoothed envelope, are shown for detection and classification objects of two classes: person and big animal (horse). It is proposed to perform the detection procedure by the non-parametric method based counting the number of spectral components exceeding the corresponding components of noise. The classification procedure based on the maximum likelihood principle permits to classify person and horse signals with high reliability.
