摘要
量子雷达是一种利用量子现象进行目标状态感知与信息获取的远程传感设备。通过引入量子增强策略,量子雷达的测量可以突破标准量子极限并逼近Heisenberg极限。首先,探讨量子力学在信息获取、传播和处理过程中的推进作用和量子远程传感器的应用需求;随后,着重介绍量子雷达的基本概念和原理,包括量子干涉测量、量子激光雷达和量子照明,对3种量子雷达体制的性能进行了分析;此外,分析量子雷达的技术要点,如量子纠缠源、量子信号的调制与检测、量子雷达的结构以及未来发展方向。
Quantum radar is a promising remote sensor that exploits quantum phenomena to perceive target information. By introducing quantum strategy into transmitter or/and receiver, its accuracy breaks the standard quantum limit, but still follows the Heisenberg uncertainty relation. The acquisition, transmission and processing of information are promoted by quantum theory greatly. In this paper, the concept and princi- ple of quantum radar, including quantum interferometry, quantum ladar, quantum illumination, are intro- duced in detail, as well as the development, classification and performance. Finally, the technological essen- tials and development direction are discussed from an engineering perspective.
