CONSTELLATION MATCHING SYSTEM AND METHOD ABSTRACT OF THE DISCLOSURE A system (10) and method for matching a set of detected points (26) to a reference constellation (20). A programmable processor (14) receives detected coordinate locations from a sensor (16) and reference coordinate locations from a reference storage device (12). The processor (14) performs a coordinate transformation from the reference coordinate frame to the detected coordinate frame and contructs a table of possible matches. Potential matches are found from the possible matches which have their difference vectors below a predefined threshold. These possible matches are then placed in a match matrix histogram (30) which is further refined to eliminate all but the best matches. The final matching then may be used to find a particular aimpoint (24) in the detected constellation (26).
