摘　　要：量子纠缠信号独特的空间关联特性可以突破经典成像所面临的距离、精度等技术壁垒.由此总结纠缠信号"鬼成像"的原理,将之引入导航领域,提出一种基于腔电光力转换器制备的杂化纠缠量子信号的成像方案.通过理论分析和仿真,相比于传统成像方式,其充分利用纠缠微波信号空间关联特性,以"非局域"的方式生成了用经典方法无法看到的图像.在弱信号探测时,信噪比高于经典方案,即成像质量优于经典方案,且具有经典方案不具备的极强的抗大气湍流扰动能力.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 cavityelectric 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 signaltonoise 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.
