| Abstract | Most high-resolution bearing estimation algorithms have been based on the assumption of a far-field source environment. When this assumption is violated, i.e., when some sources are in the near field, these algorithms generally show unsatisfactory performance. An algorithm to tackle this problem using a uniform linear array is proposed. The observed signal covariance matrix of near-field sources is equivalently viewed as a corrupted measurement of the ideal signal covariance matrix of far-field sources located at the same bearings. A far-field approximation (FFA) covariance matrix is reconstructed from the observed covariance matrix to reduce the corruptions. Therefore, existing high-resolution bearing estimation techniques (e.g., MUSIC) can be directly applied to estimate the bearings of the near-field sources. Simulation results demonstrating the effectiveness of this approach are presented.< |

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.
