Abstract: As a matter of great concern, positioning tasks can be realized with the help of quantum technologies, and these quantum schemes exhibit advantages that are impossible in classical schemes. Several quantum radar schemes have been proposed, which give new insights for positioning tasks from the perspective of quantum information. This paper reviewed those proposed quantum radar schemes according to the basic concepts and classification Especially, three typical quantum schemes, quantum positioning, quantum illumination, and three-dimensional enhanced quantum radar, were introduced in principle, and analyzed their imperative problems.

Key words: quantum positioning, quantum radar protocol, entanglement, quantum illumination, quantum radar
