中文摘要：

微波 photonic 信号产生计划基于到印射的时间和外部调整的频率被考察。我们专注于能提供频率的 tunability 的那些配置，信号的阶段，调整格式(即， 2PSK， 2FSK，等等) ，以及脉搏形状(即， UWBs- ， triangle-shaped, 并且任意形状，等等) 。

英文摘要：

Microwave photonic signal generation schemes based on the frequency to time mapping and external modulation are reviewed. We concentrate on those configurations that can provide tunability of frequency, phase of signal, modulation formats （i.e., 2PSK, 2FSK, etc.）, as well as pulse shapes （i.e., UWBs-, triangleand arbitraryshaped, etc.）.
