摘　　要：微波信号的光域产生是目前一个热门的研究课题,在通信系统、信号处理、雷达等领域有着广泛应用。分别介绍了在微波光子学领域中基于连续射频调制和基于频率-时间映射技术生成特定光脉冲信号的频域合成法和时域合成法,并对两种方法的几种具体方案进行详细介绍和对比,从脉冲重复频率的调谐能力、脉冲占空比、脉冲类型、系统结构稳定性等方面分析其优缺点。The generation of microwave signals in the optical domain is a hot research topic at present, and it is widely used in communication systems, signal processing, radar and other fields. The frequency and the time domain synthesis methods for generating specific optical pulse signals based on continuous radio frequency modulation and frequency-time mapping technology in the field of microwave photonics are respectively introduced, and several specific schemes of the two methods are introduced in detail. The advantages and disadvantages are analyzed from the aspects of the tuning ability of the pulse repetition frequency, the pulse duty cycle, the pulse type,and the stability of the system structure.
