| Abstract | Design and performance of a monostatic ultra-wideband (UWB) microwave radar system is described in this paper. Design details are presented for a novel rugby-ball antenna and UWB resistive duplexer of the radar system. The antenna is fed through the image ground plane and backed by a reflector. Intersection of two circular areas of different radii of curvature makes up the antenna element. Antenna bandwidth is determined by upper and lower radii of curvature of the antenna element. UWB (0.1-20 GHz) voltage standing-wave ratio (percent bandwidth of 198%) was achieved, which is suitable for detection of ultrashort electric pulses. An extended time sampling method was used for the receiver section of the radar system. Analysis and performance results are described for the sampling unit and resistive duplexer. Measurement results are presented for the far-field radiation of the antenna. A comparison of range measurement was performed using the UWB antenna in a monostatic radar system with a standard trapezoidal UWB bi-static configuration. The range measurement error was improved from 3.37% to 1.59% using the present rugby-ball antenna in a monostatic radar configuration |

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.
