Abstract
A multiple target correlation system for unambiguously detecting, locating and determining the orientation of an array of multiple targets or objects. The multiple target correlator provides a means for fabricating a matched filter array or multiple matched filter with multiple targets stored on a single plate and a method for interrogating this multiple target matched filter with multiple scene images thereby providing for the identification of each object or target and determining its location and orientation in coordinates that are user selectable. The multiple target correlator utilizes a multiple matched filter having two matched filters for each particular object or target stored thereon, and each matched filter is positioned at a unique angle. Since there are two matched filters for each object or target, there will be correlation at two different angles, one for each filter, and since the angular difference is unique for that object, then the difference between the matched filter angles will serve as an identification tag for that object. In addition, the angles at which the consecutive correlations occur are noted and utilized to determine the location and orientation of each of the objects.
