摘　　要：传统的无线电导航技术将无法满足高精度测角需求,而量子纠缠信号优越的特性可以突破传统无线电导航所面临的技术壁垒,由此提出了一种基于腔电光力转换器制备的杂化纠缠量子信号的测角方案,通过理论分析和仿真,相比于传统测角方法充分利用了纠缠特性对测角信号进行判别,能有效区分有用信号与无关信号,精度上优于经典方案,且具有经典方案不具备的极强的抗干扰能力。The traditional radio navigation technology does not meet the requirements of high-precision angle measurement, whereas the superior characteristics of entangled quantum signals can break through the technical barriers faced by traditional radio navigation. Therefore, this paper proposes a navigation angle measurement scheme based on hybrid entangled quantum signals prepared by a cavity electro-opto-mechanical converter. According to the theoretical analysis and simulation, compared with traditional angle measurement methods, this scheme makes full use of the entanglement characteristics in discriminating angle measurement signals and thereby effectively differentiates useful signals from irrelevant signals. Its accuracy is better than that of the classic scheme, and it also has a strong anti-interference ability that the classic scheme does not have.
