量子雷达研究新进展

The New Developments of Quantum Radar

针对传统雷达探测系统灵敏度受标准量子极限限制而无法继续提高的问题,从雷达的发射端、接收端以及发射频率等方面,通过引入纠缠态或者压缩态等量子态,重点研究了干涉式量子雷达、接收端量子增强雷达以及量子照明雷达近几年的发展状况、方向及应用。通过研究可以看出,量子雷达能够突破标准量子极限,提高测量精度,实现超灵敏探测,可用于传统目标探测和识别,以及探测射频隐身平台和武器装备等。

In view of the problem that the sensitivity of the traditional radar detection system is limited by the standard quantum limit and cannot be further improved. From the aspects of the transmitter, receiver and the transmitting frequency of radar, the development, direction and application of quantum radars, such as quantum interferometry, quantum enhanced LADAR and quantum illumination, have been investigated by introducing quantum states, i. e. , entangled state or squeezed state. According to the research, quantum radar can break through the standard quantum limit, and improve the measurement precision. It can also realize the super - sensitivity detection, which can be used in the traditional target detection, identification, and detection of the RF stealth platform and weaoon ectuioment.
