Quantum Radar Theory

As discussed in the previous chapter, traditional radar systems employ classical electromagnetic waves to detect targets. That is, the traditional radar signal is made of a large number of photons. Quantum radar generalizes the concept of radar, but this novel device operates with a relatively small number of photons. As such, its theoretical description has to be done using quantum electrodynamics.

The motivation for developing the concept of quantum radar is the potential use of quantum phenomena to increase the sensitivity of the sensing system. As we will see in this chapter, entangledphotons quantum radar appears to offer higher sensitivity. Furthermore, it seems that it is much more difficult to conduct jamming ...
