Review and forecast of quantum radar

The Radar is a kind of active remote-sensing device which has the abilities to detect and identify targets in all weathers. With the development of the radar system, the pursuit of higher SAR image quality makes the radar system more and more complicated so that the current radar systems need a revolution. Theoretical analyses show that a device processing quantum information has the potential to promote its sensitivity at utmost and the system performance would be increased as a result. This paper demonstrates the development history of quantum radar and predicts the feasibility of the quantum radar.
