| Abstract | In this paper, a new inversion approach has been proposed using the ratio of two mutually orthogonal components of recorded electric and magnetic fields: apparent admittance. This study aims at the development of a full waveform inversion algorithm in two-dimension (2D) without the precise knowledge of source functions and without any compensations of 3D nature of radar wave propagation. To alleviate local minima problems, we developed a data weighting method based on the data misfits. The developed inversion approach was firstly demonstrated through inverting 2D FDTD simulation data of crosshole radar survey with false source signatures. Further demonstrated was that the numerical data simulated in the 3D space could be inverted by the proposed 2D algorithm with the 2D FDTD forward modeling. All numerical experiments showed that the material property distribution with remarkably high accuracy can be calculated in spite of the lack of the accurate source information and no compensations of the characteristics of radar wave propagation in 3D space. |

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.
