本文提出了一种光电任意波形发生器，并进行了实验研究。它允许通过驱动光载微波信号的振幅和相位来产生预定义的波形。光学架构结合了高分辨率移频器（用于微波信号的外差生成）和空间光调制器（用于幅度和相位的并行控制）。这样的波形发生器对于目标识别或目标模拟是有吸引力的。
An optoelectronic arbitrary-waveform generator has been proposed and experimentally developed for radar applications. It permits generating predefined waveforms by driving the amplitudes and phases of optically carried microwave signals. The optical architecture combines a high- resolution frequency shifter (for the heterodyne generation of the microwave signal) with spatial light modulators (for the parallel control of amplitudes and phases). Such a waveform generator can be attractive for target recognition or for target simulation.
