| Abstract | Detection of buried landmines and estimation of depth by modeling layered media is a complex and computationally intensive task. Microwave remote sensing with the capability to penetrate subsurface and its ability to resolve landmines as well as non-lethal targets can therefore be used for subsurface landmine detection. A model based on electromagnetic scattering and image analysis techniques at X-band frequency for sub-surface detection of dummy landmines buried under a sand layer and estimation of its depth has been proposed in this paper. An extensive set of lab experiments have been carried out using dummy landmines (without explosives) and backscatter observed at different depths. The raw data is processed through a series of image processing steps, the detection is carried out using Otsu's thresholding and the depth estimated by optimizing through a GA (genetic algorithm) based electromagnetic model developed. The method does not have any requirement of separate training and test data set to train the optimizer and validate the results. The results under laboratory conditions indicate that detection of dummy landmines is possible using thresholding techniques with data generated in X band and the proposed model is capable of estimating depth of the buried landmine to a significant accuracy. |

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.
