    Abstract

    The unique spatial correlation properties of quantum entangled signals can overcome technical barriers, such as those presented by the distance and accuracy, encountered by classical imaging approaches. Therefore, herein, the principle of “ghost imaging” of entangled signals is summarized and is then introduced in the field of navigation. Accordingly, an imaging scheme of hybrid entangled quantum signals generated using a cavity-electric photoelectric light converter is proposed. In contrast to the traditional imaging method, herein, based on theoretical analyses and simulations, the spatial correlation characteristics of entangled microwave signals are completely utilized, and the images that cannot be observed by classical methods are generated in a “nonlocal” manner; correspondingly, the signal-to-noise ratio is higher than that of the classical scheme when weak signals are detected. That is, the imaging quality is better than that of the classical scheme, and it has the ability to resist atmospheric turbulence disturbances unlike the classical scheme.
