| Abstract | In subsurface radar applications, it is often experienced that the requirements for the resolution and the penetration depth contradict each other. For example, pre-excavation survey of archaeological sites may require one to detect buried objects of the order of 10 cm at a depth of 1 m. In such a case, the compromise will be the use of around 500 MHz, for which the target is on the order of a radar wavelength. We refer to the target in such a situation as a 'small object'. It is thus hard to identify the shape of the object with conventional signal processing such as the synthetic aperture method. Our objective is to develop a robust high-resolution imaging algorithm applicable to targets whose dimension is close to the radar wavelength. In order to avoid instabilities in super-resolution techniques, we limit the freedom in the estimation by properly modeling the target as well as the parameters of the medium. |

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.
