Engineering Physics Annotation << Back Tracking of targets paths in seismic security systems K.V. Kostenko, V.F. Shevtsov Master phases of the signal processing in seismic security systems are given. The principles and the mathematical apparatus of targets coordinates determination in systems on discrete seismic sensors are stated. An influence of casual and technical factors on calculation precision of a target position is observed. The principles of calculation of speed, target driving direction and plotting of its path are specified. Keywords: security systems, seismic systems, seismic sensors, seismic signal, information processing, coordinates determination, plotting of paths. E-mail: kostenko@dubna.ru
