| Abstract | One-step passive localisation methods are verified to outperform the conventional two-step methods in terms of estimation accuracy and identifiability. However, the existing one-step algorithms still cannot work in the scenario where the number of emitters exceeds the total number of sensors from all the base stations. Based on a spatio-temporal processing procedure, the authors propose a novel localisation model, which has the form of multi-dimensional harmonic retrieval. By utilising multi-dimensional spectrum estimation techniques, the underdetermined localisation problem can be handled thanks to the increase of model's degree of freedom. To further improve the identifiability, a nested-array-based localisation model is also given based on the multi-dimensional processing framework. Simulation results demonstrate that the novel-model-based Capon algorithm can achieve higher localisation accuracy without the prior knowledge about the number of emitters, and is robust to the correlated noise. |

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.
