초록

Recently, research and study on the development of 6th generation fighter aircraft have been actively discussed, mainly in the US, Europe, and China. Accordingly, the next-generation radar system, which is regarded as a key component of the 6th generation fighter aircraft, has been also discussed. In particular, the advanced target detection and stealth detection capabilities of quantum radar systems announced in the Chinese press opened up the possibility of a quantum radar system as the next generation radar system.Quantum radar extends the concept of conventional radar systems and detects targets based on the transmission and reception of quantum states of photons.Accordingly, it can detect targets with a relatively small number of photons, enable to provide neutralization of stealth and electronic warfare techniques and enhanced security. Therefore, in this paper, we review the research trends of quantum entanglement, which is the core of various quantum technologies, and then review quantum illumination, a key element of quantum radar systems. Based on the theoretical and experimental results of quantum illumination studied up to now, we analyze the technical advantages and implemental difficulties of applying quantum illumination to radar systems.
