| Abstract | Due to a large number of beam-steering units and complex interfaces of a spaceborne phased-array radar, the fault location in joint tests is difficult, the troubleshooting efficiency is low, and the progress of the project is difficult to guarantee. To solve the above problems, this study presents a design scheme of full-array beam-steering test bench based on OpenVPX architecture. This solution utilises OpenVPX architecture's advantages of good versatility, strong scalability, high transmission bandwidth, and rich I/O ports. It adopts commercial off-the-shelf modules that conform to the OpenVPX standard to build the hardware system. The serial rapid I/O switching technology is used to implement high-speed interconnections and full-function automated testing from the primary beam-steering unit to the secondary beam-steering units. Compared with the existing test methods, this test bench meets the development trend of commercialisation, interchangeability, interoperability and adoption of open industry standards for user testing requirements, which greatly improves the efficiency of full-array beam-steering testing and reducing labour intensity. The average test period is reduced from more than one week to less than one day, achieving the design requirements for rapid test and accurate fault location. |

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.
