| Abstract | Clutter filtering according to distinct Doppler echoes is a major measure to deal with the interference in radar signals caused by the rotating blades of nearby wind turbines. For the problem that the traditional simulation method of scattering point superposition model could not simulate the continuity of induced current on the blade's complex surface, the authors proposed a new simulation method of Doppler echoes based on scattered electric field calculation and expounded the basic principle and implementation steps of the method. First, they found the correspondence between the electric field's complex amplitude vector and the echo signal by deducing the equations of echo signal and scattering electric field; second, they used the quasi-static technique, the hybrid algorithm of physical optics and method of moment to achieve an accurate solution of the scattered electric field sequence; finally, the authors used the short-time Fourier transform to obtain the time–frequency domain data of blades Doppler echoes. The result was compared with data obtained from the scattering point superposition model and in-field experiments, and the accuracy of the proposed method was verified. |

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.
