Abstract: A system for detection of human or vehicle activity comprising at least one sensor adapted to generate a signal and at least one processor operating to denoise the signal; generate an autocorrelation of the signal; partition the signal into a predetermined number of overlapping segments to form a time series of data; generate symbols for the overlapping segments; compare the pattern of generated symbols with known predetermined patterns of symbols representing human or vehicular activity; determine whether a threshold probability is exceeded which attributes the data signal to human or vehicular activity; analyze the patterns presented in the data signal by transforming the patterns of symbols into states; determine the transitions between states; and classify the signal as to being attributable to human or vehicular activity based upon the transitions between states. A method of detection and classification of sensor data signals via detecting patterns using time series analysis.

Abstract: A method and system for detecting targets comprising at least one first receiver for receiving radiation, the radiation comprises beams of radiation spaced horizontally; at least one second receiver for receiving radiation, the radiation comprises beams of radiation spaced horizontally and vertically such that the beams of radiation received by the second receiver travel through different predetermined heights from the horizontal plane; at least one processor for receiving data from the first and second receivers, the at least one receiver operating to locate a target passing in the vicinity of the first and second receivers and determine the height of the target based upon the recordation of certain of the beams at a predetermined heights relative to the horizontal plane and the width of a target based upon the horizontal spacing of the beams.
