定位测量一直是人们关注的问题，将量子技术应用于定位任务有望展示出经典定位方案无 法达到的优势。目前，已有部分量子雷达方案被提出，展示了科研工作者从量子信息角度对定位 测量的新思考。本文总结了部分已有的量子雷达方案，介绍了相关方案的概念和分类，并着重对 量子定位、量子照明和三维增强雷达三种方案的基本原理进行论述，同时分析了各方案的优势以 及亟待解决的问题。

As a matter of great concern, positioning tasks can be realized with the help of quantum technologies, and these quantum schemes exhibit advantages that are impossible in classical schemes. Several quantum radar schemes have been proposed, which give new insights for positioning tasks from the perspective of quantum information. This paper reviewed those proposed quantum radar schemes according to the basic concepts and classification Especially, three typical quantum schemes, quantum positioning, quantum illumination, and three-dimensional enhanced quantum radar, were introduced in principle, and analyzed their imperative problems.
