| Abstract: | Radar is the main method to achieve target detection and recognition. Multifunction, high precision, reconfigurability and real time are the development trends of radar detection. The bandwidth bottleneck of electronic technology is a limiting factor to the improvement of radar system in operating frequency and bandwidth. The inherent characteristics of photonic technology, such as large bandwidth, low transmission loss, and anti-electromagnetic interference, make it a key technology to break through the electronic bandwidth bottleneck and illuminate the future of radar. This paper summarizes the main research progress of microwave photonic radar systems and introduces the critical technologies of the photonic time-stretched coherent radar (PTS-CR). The future prospect of the development of photonic radar technologies is also discussed. |
