| Abstract: |
| This paper expounds the development trend of cross-generation radar technology and typical cha-racteristics of the fifth-generation radar, such as array, broadband, network, synthesis and intelligence. The advantages of microwave photonic technology and the incremental efficiencies for radar system in the typical application scenarios are summarized. The main problems to be solved in practical applications of photonic radar are analyzed, such as link performances, integration level, array, and engineering. And the ideas and basic methods to solve these problems are given respectively. Finally, the basic architecture, implementation methods and technological development suggestions of the future all-optical radar based on new integrated coherent light system are given. |
