| Abstract | In recent times, various theoretical and experimental studies have been carried out in order to address the relationship between amplitude attributes of the `direct wave' propagating at the interface in bistatic ground-coupled radars (the so-called `early-time signal') and the relevant shallow-soil permittivity. This issue is extensively analyzed here for the first time by means of an accurate and efficient numerical approach based on a CAD tool. The flexibility of the approach allows us to investigate in wider terms the role of the various physical parameters that affect the early-time signal features (type, location, and distance of the antennas, transmitted waveforms, etc.), in addition to the electromagnetic contrast between upper and lower media. Quantitative results are derived in order to clearly establish which are the more revealing signal attributes that enable for predictable correlation to the ground permittivity values and what kind of functional relations can be outlined. Novel and reliable information can thus be achieved on the actual potential of the `early-time method' for efficient subsurface non-destructive testing. |

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.
