摘　　要：RF光子元件技术的最新研究发展将会对未来的雷达系统结构产生很大的影响。本文重点介绍了采用光子技术研发的低噪声系数、大动态范围RF分配链路和延迟线，以及低相位噪声RF振荡器和快速调谐RF滤波器的最新性能，对比电子RF前端技术，对体积、重量、功率进行分析，最后讨论了可应用于雷达系统的其他RF光子技术和更广泛的雷达系统所要求的光子器件的进一步改进。The latest development trends of RF photonic component technologies will have a significant impact on future radar system architecture. In this paper, current performance of low noise figure and high dynamic range RF distribution links and delay lines, low phase noise RF oscillators, and fast tunable RF filters developed using photonic technologies are highlighted. Performance comparisons with electronic RF front - end technologies are provided including size, weight and power considerations. Finally, other RF photonic technologies applicable to radar systems and further photonic device improvements required for more pervasive radar system use are discussed.
