量子雷达探测中的目标特性

量子雷达具备与经典雷达不同的探测原理和特征,有望为经典雷达探测中面临的难题提供新的解决途径,因此具有重要的应用潜力。目标特性是影响雷达探测效果和获取目标信息的重要研究内容,在量子雷达的探索过程中,对量子探测中目标特性的研究,目前还处在早期,缺少系统的研究。文中尝试对量子探测中的目标特性研究进行初步讨论:基于量子探测中的目标特性概念,讨论量子雷达中量子态信号检测下的目标特性,并对偏振态、纠缠态和压缩态等信号下的量子目标特性进行分析,为以后的研究工作提供参考。

Target Properties in Quantum Radar Detection

Quantum radar has different characteristics and principles, so it works in a different way from classical radar system. With the prospect to solve many challenges raising in radar detection field, quantum radar has shown great potential to pave a way. As target properties influence the detection results and target identities, it is an important issue in quantum radar research. However, the research in this issue is seldom reported. In this article, the quantum target properties are discussed in a preliminary way. We are based on the concept of quantum target properties to discuss the different form of quantum target properties corresponding to different kind of quantum radar signals, including the non-classic states such as entangled state or squeezed state. This article attempts to touch the feature of quantum target properties for guiding the design and utilization of quantum radar in the future.
