| Abstract | To solve the inverse problem in ground penetrating radar by minimization of a cost function in an iterative process, a fast solver for the direct problem is required. For this purpose the authors propose a hybrid method which is based on spectral domain methods in conjunction with the exact solution for dielectric circular cylindrical objects. The advantage of spectral domain methods is, that they can describe the ground as well as the inevitable air gap between the antenna and the ground as a set of dielectric layers of defined thickness and infinite lateral extents. No absorbing boundaries are required to limit the size of the structure. Multiple reflections between cylinder and the air ground interface can by determined by an iterative procedure. The total electric field is calculated in the plane of antenna as the result. The paper includes the description of the method as well as the comparison of calculated results to measurements of hidden objects shallow in the ground, obtained with a monostatic single frequency CW radar sensor. |

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.
