A Ultrawide-Band VCSEL-Based Radar-Over-Fiber System
In this paper, an ultrawide-band (UWB) low-cost Radar-over-Fiber (RaoF) system is presented which exploits optical links based on directly modulated-VCSELs for radio frequency signal distribution from/to the base station to/from the transmitter/receiver front-end. The system, which includes packagin...
