1. A system for locating and tracking a path of an object traveling in space originating from a known launch location comprising: a) first and second linear sensor arrays operating in the visible or near-infrared spectrum and having respective lenses therein, each sensor array being separated from the other by a known baseline; b) each sensor array having a plurality of directed pixel sensors positioned to provide individual pixel fields of view which collectively provide a planar field of view for each sensor array, said planar field of view being defined by the respective lens; c) the respective sensor arrays being mounted at a known separation from the launch location so that the individual planar field of view of the first sensor array substantially overlaps with the planar field of the second sensor array to provide one shared, substantially common planar field of view, the common planar field of view having a known angle of inclination in space; d) signal generation means associated with each sensor array to generate signals corresponding with the detected presence of the object passing through the planar field of view of each sensor array in terms of position, and at least one of said arrays also generating a signal corresponding with the detected time of the object passing through the planar field of view; e) time sensing means for recording the time at which the object leaves the known launch location, and f) electronic processing means connected to receive signals from said signal generation means for obtaining the time of penetration of the common field of view and for obtaining the positions of the object as it passes through the common field of view, and connected to receive a signal from the time sensing means as to the time at which the object has left the known launch location and, based thereon, the electronic processing means, and being provided with means for calculating a calculated extended path for the object as it passes immediately beyond the respective, common planar fields of view; g) display means connected to the processing means to provide a display based upon the calculated extended path, and wherein the electronic processing means uses the position of the known launch location with respect to the two sensing arrays, the point of penetration of the object through the substantially common planar field of view, and the delay between the time at which the object leaves the launch location and the time at which the object penetrates the common field of view to calculate the velocity of said object therebetween and, based upon the path between the known launch location and the common planar field of view being a generally parabolic path, to thereby determine the calculated extended path in space of the object as it passes immediately beyond the respective, common planar fields of view.
