| Abstract | Ultra wideband (UWB) radar with high range resolution is promising for short-range 3-dimensional (3-D) imaging applications, such as a sensor for rescue robot in disaster scene. We have already proposed the efficient 3-D imaging methods as range point migration (RPM) method, which has a definitive advantage for SAR or time-reversal approaches, in terms of computational burden, high accuracy and high spatial resolution. However, if the aperture size is insufficient, this method cannot image the whole target structure. Conversely, useful information about the target structure can be extracted from the full polarimetric data. Therefore, this paper proposes a novel method that expands reconstructed RPM images by exploiting the full polarimetric data. This method introduces the ellipsoid-based scattering analysis and estimation, and significantly expands the original image by the RPM method by an aggregation of parts of ellipsoids. The results of numerical simulation based on 3-D finite difference time domain (FDTD) analysis verify the effectiveness of our proposed method. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
