| Abstract | The pulse-compression is a technique mainly used in sonar, radar and echography to augment the range resolution as well as the signal to noise ratio. This is achieved using a matched-filtering of the received signal with the bandpass transmitted signal. Taking into account the main assumptions of the matched filter theory, the use of the bandpass transmitted pulse as matched filter's impulse response is only available if the useful signal is well known and if the noise is white, which is not the case in practice. For this reason, we propose to improve the classical pulse-compression technique using the stochastic matched filter, which ensures a maximization of the signal to noise ratio, when the useful signal is a realization of a random process and the disturbing signal a colored noise. Results obtained on synthetic and real data are proposed and discussed. |

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.
