Abstract: The traditional radar scheme is based on electromagnetic wave signal transmission theory,target location and other parameters measurement are realized by detecting the electromagnetic wave echo signal reflected by objects in space.The quantum radar under the framework of quantum technology has more obvious advantages in improving radar accuracy,response speed,anti-jamming and anti-stealth compared with the traditional radar.The principle,development and application of quantum technology in radar are introduced in this paper,and three kinds of quantum radars based on advanced quantum measurement technology in china are introduced emphatically.By expounding the case and analyzing its principle,which provides a new idea for the further development of quantum radar in the future.

Key words: Quantum measurement, Quantum radar, Development trends
