| Abstract | The Doppler effect caused by the dynamic rotation of the wind turbine blades is an important evidence for the identification of the wind farm clutter at the nearby radar stations. Due to the difficulty in obtaining the accurate radar echo signal of wind turbine blades by the existing methods, the accurate Doppler spectrum cannot be obtained. For that reason, the problem of accurate simulation of radar echo for wind turbine blades is avoided, and a new idea is proposed to solve the Doppler spectrum by using the dynamic radar cross section (RCS) of the blade through the study of the mechanism of the Doppler effect. Based on the matured dynamic RCS exact solution techniques of electrically large size targets, the time-domain RCS curve of blades in the dynamic motion state is obtained with the quasi-static method, using the hybrid algorithm of physical optics (PO) method and of equivalent currents method. Based on this method, calculation and analysis of the wind turbine blades' Doppler characteristics in the rotation, torque conditions provide a reference for the recognition of radar target signal of the wind turbine, the reduction of RCS, and wind farm clutter suppression of the nearby radars. |

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.
