The JTC technology deals with the problem of target tracking and target classification simultaneously within a unified framework.The fundamental idea of the JTC technology is that by taking advantage of the mutual exchange of useful information between the tracker and classifier,significant improvements in performance of both target tracking and target classification can be expected.The principle of JTC technology is introduced.The existing JTC technologies are broadly categorized into two classes,i.e.,point-target-motion-model-based JTC and rigid-target-motion-based JTC,which are then compared in detail.The advance of the JTC technology is surveyed with comments on some related literatures.Finally,some opening topics of the JTC technology are discussed.
