| Abstract | Ground-based radar can make high-precision and real-time monitoring of micro changes in the observation area. It has been actually applied in various industries such as land, open-pit mines, water conservancy dams, and highway bridges. The basic principle of the ground-based radar is to transmit and receive electromagnetic wave signals in the distance direction and to perform pulse compression, a synthetic aperture is formed in the azimuth using the motion of the platform, and the electromagnetic wave signals are coherently accumulated to form a two-dimensional image. In this article, a fast and efficient pseudo-polar coordinate format imaging algorithm is proposed. First, in order to prevent defocusing, the authors use the Taylor approximation and the accuracy difference of the phase change due to the distance approximation is analysed. Second, the 2-D fast Fourier transform effectively achieves uniform sampling of data. The technique is validated with numerical simulations. |

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.
