Abstract | A new multi-objective optimisation algorithm called non-dominated sorting and local search (NSLS) algorithm is proposed for uniformly excited aperiodic array synthesis here. Two design cases of uniformly excited linear and planar array synthesis are conducted to verify the outperformance of NSLS. Synthesis results indicate that NSLS is able to obtain the lowest maximum sidelobe level (MSLL) and the deepest null depth level in linear array design case, along with the lowest MSLLs in two planes of radiation pattern in planar array design case compared with the other latest algorithms. In addition, the convergence performance and computational costs of NSLS in the design cases are investigated. The synthesis results combined with excellent convergence performance and low computational costs of NSLS make it a reliable and promising optimisation algorithm for uniformly excited aperiodic array synthesis. |

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.
