Preliminary experimental result of optical fiber connected passive primary surveillance radar

This paper describes a new radar system concept using a radio-over-fiber (RoF). The proposed system is an Optical Fiber Connected Passive Primary Surveillance Radar (OFC-PPSR) which is based on the passive bistatic radar. Separated receiver unit uses scattered waves from aircraft and radar reference data. Radar reference data transmitted by RoF include radio frequency (RF) of transmitter unit and processing data such as rotating radar angle. In this paper, we present a principle of the OFC-PPSR and show experimental system which has been deployed in Sendai airport. We show the preliminary experimental result of the proposed system. It will be shown in the experimental result that the proposed system can detect moving aircraft.
