配置并演示了采用光纤无线电技术操作的 300 GHz 调频连续波 (FM-CW) 雷达系统。基于光学频率梳生成的集中式信号发生器可提供高精度 FM-CW 雷达信号。光信号很容易通过光纤网络传输到雷达头。基于光调制器的光频梳发生器被用作通过光调制技术从微波信号到300GHz太赫兹信号的光倍频器。在研究中，我们讨论了太赫兹波多基地雷达系统的网络、信号发生器和远程雷达头的配置。
300-GHz frequency-modulated continuous-wave (FM-CW) radar system operated by radio over fiber technologies is configured and demonstrated. Centralized signal generator, which is based on an optical frequency comb generation, provides high-precise FM-CW radar signal. The optical signal is easy to be transported to radar heads through an optical fiber network. Optical-modulator-based optical frequency comb generator is utilized as an optical frequency multiplier from a microwave signal to a 300-GHz terahertz signal by an optical modulation technique. In the study, we discuss the configuration of the network, signal generator and remote radar head for terahertz-wave multi-static radar system.
