| Abstract | There are a large number of high-energy particles in the space. These high-energy particles induce a single-event upset effect on DSP, FPGA, and other programmable digital controllers inside the beam-steering unit, which can produce unpredictable and erroneous influences, thereby reducing the reliability of space-borne-phased array radars. In order to solve the above problems, this study presents a design of beam-steering unit based on a kind of application-specific integrated circuit (ASIC). By using the advantages of ASIC circuits such as strong radiation resistance, high integration, and low power consumption, this solution adopts an anti-irradiation ASIC chip as a controller, and anti-irradiation RS422 transceivers are used to complete interface conversion for receiving data and transmitting data. The beam refreshing and telemetry functions between the beam control computer and the 24 microwave modules are realised finally. The test result shows that the phase distribution time is <30 μs when the clock is 3.125 MHz, and the falling edge of sampling pulse is located at half the length of a data symbol, ensuring data hold time long enough to sample correctly. |

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.
