Experimental prototype for MSPSR based on optical fiber connected passive PSR

Multi-static primary surveillance radars (MSPSR) are being actively studied to deliver surveillance technology for civil aviation. By using multiple receivers, the performance of PSR detection can be improved, as the reflection characteristics, which change with aircraft position, can be suitably synthesized. In this paper, we report experimental results from our proposed optical-fiber-connected passive PSR system with transmit signal installed at the Sendai Airport in Japan. The proposed system is capable of detecting moving aircraft, as demonstrated by a comparison of the experimental results with real surveillance data.
