Gridlocking and correlation methods and arrangements
First Claim
1. A method, comprising:
- receiving a reference image and a comparison image, wherein the reference image comprises track data of a first track about a first object and the comparison image comprises track data of a second track about a second object, the first track sensed substantially simultaneously with the second track;
displaying the reference image and the comparison image as coherent images at the input plane of an optical correlator;
detecting an interference intensity substantially proportional to a cross-correlation of the reference image with the comparison image; and
associating the first object with the second object based upon a comparison of the interference intensity with a second interference intensity, wherein the second interference intensity is substantially proportional to a cross-correlation of the reference image with a second comparison image.

Abstract
The present invention is in the area of tracking objects with systems such as correlation, gridlocking, optical correlation, and combinations thereof. Embodiments encompass systems of process and/or equipment to correlate objects and gridlock sensors with images based upon track data from sensors. In many of the embodiments the sensors may comprise radars, global positioning systems, laser target designators, seismic sensors or systems of seismic sensors comprising hydrophones and geophones, and other similar systems. While embodiments may comprise an optical correlator, many embodiments perform one or more analyses statistically. Embodiments may refine coordinate transformations for the sensors and may account for errors by comparing a full or partial history of the track data associated with the same object from the same sensor. Further, many embodiments comprise software that can execute on a laptop, desktop, or similar computer.
