基于被动量子雷达的隐身目标探测研究

未来战场,将是隐身武器的较量,不论是有人机、无人机,还是巡航导弹、弹道导弹,都朝着隐身化方向发展.传统雷达在对付这些隐身目标时存在无法突破的性能极限.笔者将被动雷达与量子技术结合,提出被动量子雷达,分析其对隐身目标探测的机理.采取超导电路技术实现对微波光量子转换处理,并使用SVI和PSA量子增强接收技术,以及JPA技术实现高灵敏度微波信号接收,被动量子雷达可将系统灵敏度最大提高大约4个数量级.分析结果表明提出的基于被动量子雷达的隐身目标探测原理可行,具有很强的应用潜力.

Study on stealth target detection based on passive quantum radar

There exist a contest of the stealth weapons in the future battlefields, and the manned plane or the unmanned plane, cruise missile or trajectory missile are all developing in the direction of stealth, which makes it difficult for the traditional radar to detect them. In this paper, the passive quantum radar was presented which integrated the quantum technique and passive radar, and its mechanism of stealth target detection was analyzed. Microwave signal was quantized by using the superconducting circuit technique and high sensitivity of the receiver was realized by taking full advantage of advanced methods, including SVI and PSA of quantum enhanced processing at receiver, as well as JPA technique. By using passive quantum radar, the system sensitivity had been improved almost by 4 order in comparison with that of the tradition radar. The analyzed results show that the proposed method of target detection based on passive quantum radar is feasible, and it has good applicable potential.
