| Abstract: |
| Microwave photonic radar can break through the electronic bottleneck with the aid of photonic technology, and the realization of integrated photonic system is the inevitable development trend of microwave photonic radar in the future. Benefiting from the unique linear and nonlinear optical characteristics, optical microresonators with ultra-high quality factor can realize the optical domain control of broadband microwave signal within a very small volume, which makes it the key component of integrated microwave photonic radar system. They have important application values in such functional units as microwave photonic filter, photonic generation of microwave signals, photonic-assisted channelization receiver, and optical control beamforming. Besides, they also have broad application prospects in systems such as terahertz radar, lidar and other systems in the future. |
