This chapter is devoted to quantize the radar. In other words, the quantum radar is introduced to obtain a new view of the radar theory. Indeed, microwave photons were quantized in the earlier chapters. In this regard, the radar theory which is based on the scattering theory can be tackled from the point of view of the quantum mechanics. This chapter attempts to answer this question in the form of the mathematical equations. In doing so, the Entangled quantum is introduced to understand the radar theory in the view of a quantum mechanics. This chapter also delivers the radar quantum equation. The new concept of the quantum radar illumination is also proposed.

The conventional radar theory relies on the classical electromagnetic wave theory to run. On the contrary, a quantum radar will relie on the quantum mechanic theory to run. A quantum radar that uses the quantum illumination based on photon entanglement enables to get a better detection sensitivity. In this paper, we highlight the influence of the propagation environment on the quantum illumination radar scheme. Our approach consists in describing the quantum information evolution inside the radar and the entanglement rate with a mathematical parameter which represents the interaction strength of the propagation medium on the quantum system used by the radar.

Quantum radar is a remote sensor that exploits quantum phenomena to perceive target in the distance and receive its state information. In this article, the concept and principle of quantum radar are introduced in detail, including interferometrie quantum radar, quantum ladar and quantum illumination radar. And it is proved in theory that quantum radar can beat standard quantum limitation and surpass classical radar.
