Abstract

The image tracking performance of a coherent infrared radar is presented. Heuristic derivations are presented for the tracking accuracy versus image signal-to-noise ratio of centroid, balanced gate, correlation, and template correlation trackers. Expressions for the image signal-to-noise ratio versus carrier-to-noise ratio are obtained for intensity images, thresholded intensity images, range images, and velocity images. Centroid trackers using any type of imagery are shown to yield tracking accuracies which degrade as the target gets larger and are therefore inferior to the other correlation-type trackers. Balanced gate, correlation, and template correlation trackers can all provide tracking accuracies much finer than a pixel. Thresholded intensity, range, and velocity images provide better tracking performance than simple intensity images.
