| Abstract | Since the Concorde supersonic aircraft accident in 2000, the threat of Foreign Object Debris (FOD) on airport runways has been focused on. The FOD detection system is expected to prevent such the tragedy. In order to keep the airport runways clean and safe, authors are developing radar to detect small metallic objects on the airport runway surface. Millimeter-wave radar is the first candidate for this purpose because of its high detection resolution. However, the radar surveillance range is generally limited due to the high frequency attenuation and the low power devices. This paper proposes a new concept of FOD detection millimeter-wave radar using a Radio over Fiber (RoF) system. The concept overcomes the attenuation problems by connecting a local signal generator and the millimeter-wave radar module with optical fibers. The optical fiber propagation loss is much less than the free space propagation loss of radio frequency (RF), thus the completely new FOD detection system can be composed by applying the RoF system. Measurements of a prototype system, 94 GHz millimeter-wave radar connected by optical fiber, show the possibilities for the new airport application especially in terms of detection sensitivity. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
