| Abstract | This paper reports the findings of a comparative investigation of two versatile echo suppression techniques applicable to general antenna near field measurement scenarios with echoes of unknown origin. Both techniques are based on spatial filtering of the measured field taking advantage of the apriori knowledge of the antenna size and can be applied to near field measurements in any canonical scan configuration. The first technique takes advantages of the spatial filtering properties of the spherical waves expansion of the measured field. The second method is based on the reconstruction of equivalent currents and implements the spatial filtering as a direct consequence of the selected size and shape of the reconstruction surface. The benefit of using redundant data in both techniques as a mean to achieve further echo reduction in spherical near field scan geometry is examined with particular attention. The investigation has been accomplished with measured data on a SATIMO wideband horn using different sampling of the full sphere. |

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.
