| Abstract | Considering a time difference of arrival (TDOA) localisation system, it is well known that the accuracy depends on the transmitter–receiver geometry, time differences estimation error and the selection of the localisation algorithm. Although many studies related to TDOA estimation and emitter location finding can be found in the literature, the effect of transmitter–receiver geometry on positioning accuracy has not been investigated sufficiently. Most of the studies focused on figuring out the optimum receiver arrays by minimising the Cramer-Rao lower bound (CRLB) or maximising the Fisher information matrix. In this reported work, depending on the target position, the optimum receiver arrays are dynamically oriented. By using particle swarm optimisation (PSO) the target is localised and the offset angle which makes the CRLB minimum is determined. After rotating the receiver array by the offset angle, the target is localised again. At the end of the process, a significant decrement in the positioning error is obtained. To show the effectiveness of the proposed method, a uniform angular array and a cross array are selected as optimum two-dimensional geometries. |

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.
