A new radar system using a radio over fiber (RoF) is proposed. The proposed system is optical-fiber-connected passive primary surveillance radar (OFC-PPSR), which is based on a passive bistatic radar approach and uses RoF technology. A separate receiver unit uses the waves scattered from aircraft and the radar reference data transmitted by the RoF. The reference data include the radio frequency signals of the transmitter unit and the processing data of the controller unit, such as radar rotation angle. We first present the principles of OFC-PPSR and the experimental system, which was deployed at the Sendai airport in Japan. Moreover, we present some preliminary experimental results obtained with the proposed system. The proposed system is capable of detecting moving aircraft, as demonstrated by a comparison of the experimental results with real surveillance data.
