摘要
量子雷达是一种利用量子资源提升探测性能的新体制雷达,它是经典雷达的升级改进,在信号的调制、传输、接收和检测的原理上都与传统雷达有较大区别。文中从量子物理理论出发,提出了量子雷达的信号回波和背景噪声的一般公式,研究了量子雷达信号检测的一般方法与极限性能,在此基础上提出了量子雷达的一般性方程,并结合在单光子检测雷达这一具体问题上的应用,对量子雷达方程进行了阐释,定量分析了量子雷达相比于经典雷达在探测威力上得到的提升。文章最后对量子雷达方程与探测机理进行了总结。
Quantum radar is a new concept radar that uses quantum resources to improve detection performance.It is an upgrade and improvement of classical radar.It is quite different from traditional radar in signal modulation,transmission,reception and detection.Based on the theory of quantum physics,in this paper the general formula of signal and noise of quantum radar is proposed,the general method and performance limit of quantum radar signal detection are studied,the general equation of quantum radar is proposed,and the equation of quantum radar in combination with the application of single photon detection radar is explained.The improvement of detection range of quantum radar compared with classical radar is analyzed quantitatively.At the end of this paper,the quantum radar equation and detection mechanism are summarized.
