I. Mechnikov National University popup.description2 The development object is the noise-resistant registration and recognition of person and vehicles movements at distances up to 40 - 50 m. The purpose of the STD is to create an autonomous small-sized seismic system for detecting and recognizing the person and vehicles movements. Development methods combine experimental and theoretical studies of the seismic information channel and are based on the sequential development of recognition algorithms and models of the seismic system, the making of the system experimental samples and their experimental testing. The main results of the development: • the influence of climatic conditions, soil condition and physical disturbances on the seismic signals parameters from moving objects is theoretically and experimentally determined; • based on the established differences in the nature and time parameters of seismic signals from moving person, animals and vehicles, the noise-resistant program algorithms for the detection and recognition of person and vehicles have been developed; • on the basis of modern circuit solutions, the seismic signal processing unit of the seismic system has been developed; • the piezoelectric seismic transducer has been developed for the seismic system; • the testing of the manufactured experimental sample of the seismic system showed that its parameters satisfy the requirements of the technical task: the person detection range is 40 m and the vehicle detection range is more than 50 m; the supply voltage is 3 V; 6 months uptime; the operating temperature range is from -40 оС to +50 оС; system volume is 92 cm3 and weight is 0.29 kg. These parameters correspond to the best world samples, and some of them (detection range at similar sizes of systems) are even better, than analogs have; • the scientific and technical documentation for the seismic system is developed. Ukraine does not produce seismic small-sized systems for detecting moving objects, both for reconnaissance purpose  Product Description popup.authors Lepikh Jaroslav I Maximov Olexander O Reut Olexander V Snigur Pavlo O Tkachenko Oleg V Fastykovsky Pavel P popup.nrat_date 2021-02-15 Close
