Summary: 
The distributed-type optically-connected 96 GHz millimeter-wave radar system for foreign object debris detection on the airport surface is newly proposed. First, the fundamental concepts of the proposed FMCW radar system are discussed. The system consists of a central unit and several antenna units, which is connected by optical fiber networks based on radio-over-fiber technology. Then, a long distance millimeter-wave signal transmission is achieved by utilizing an optical frequency multiplier and an erbium doped fiber amplifier, while maintaining a high carrier-to-noise ratio and a low phase noise characteristics. Finally, a maximum 4 cm range-resolution performance is confirmed by the measurement.
