| Abstract | In this paper, we introduce an adaptive sensing method to a landform using a ground reflection of a ground penetrating radar (GPR). When GPR scans a ground surface, an antenna of GPR should be put on a ground as an ideal condition. The farther an antenna is put away from a ground, the shallower the sensing depth becomes, because a ground surface reflects most of the electromagnetic wave radiated by the antenna. Practically an antenna should be manipulated, keeping a small distance from a ground in order to avoid a collision with a ground. Besides, the distance should be controlled so as to observe the ground reflection at a constant position in B-scan image, which is eliminated by a simple algorithm. There are many sensors to measure a ground configuration, but we propose an adaptive sensing which does not require any additional sensors such as laser range finder. In addition, the ground reflection in B-scan image is precisely eliminated by manipulating the sensor head according to GPR sensor information. We show some experimental results to confirm its effectiveness and its performance. |

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.
