The present invention is in the area of correlation of tracks from different sensors or sensor systems. Embodiments encompass systems of process and/or equipment to format tracks from more than one sensor to be compared or correlated by statistical and/or optical correlation techniques to determine redundant or duplicate tracks. Embodiments may take into account determinations or calculations to refine coordinate transformations for the sensors and may take into account errors in those determinations by comparing a full or partial history of the data from tracks associated with the same object from the same sensor. Further, many embodiments comprise software that can execute on a laptop, desktop, or similar computer.
