摘　　要：近年来,微波光子技术在雷达、通信和电子对抗中的应用得到了越来越多的关注。本文简单介绍了微波光子技术的发展情况和优势,对微波光子技术在雷达相控阵工程应用中存在的光电/电光转换损耗大、集成度低、通道一致性差、成本高昂等问题进行了探讨,给出了微波光子技术在雷达相控阵中三种典型的应用场景,并针对目前存在的问题,提出了促进微波光子雷达相控阵推向工程应用的关键技术,包括高效的电光/光电转换、高性能的射频光传输和光电混合集成等。希望通过关键技术的突破,促进微波光子技术在雷达相控阵中实现大规模工程应用。Recently, the applications of microwave photonic technique in radar system, communication system and electronic warfare have drawn a lot of attention. In this paper, the developments and advantages of microwave photonic technology are introduced firstly. Then, the limiting factors of the engineering application of microwave photonics in radar phased array are demonstrated, such as huge electro-optic and optic-electro conversion loss, low integration, poor channel consistency, high cost, etc. Next, we propose three typical applications of microwave photonics in radar phased array. To overcome the existing limits, some key technologies should be developed including high-efficiency electro-optic/optic-electro conversion, high-performance microwave photonic links and hybrid-integration. We hope that with the development of these key technologies, the microwave photonics could be widely applied in the radar phased array.
