| Abstract | Radar is a well established tank level gauging technique. Today, a shift towards more demanding measurement applications can be observed. As a result, novel radar signal processing algorithms emerge. One of the most challenging tasks for tank level gauging systems is separation of closely spaced targets, especially with the given bandwidth limitations set by both legal means and technical feasibility. Superresolution methods are expected to overcome the inherent resolution limits of Fourier transform based algorithms. However, they are fairly complex, making adaptation to real world radar signals a tedious and complicated task. Furthermore stability problems occur, mainly caused by the necessary a priori model-order estimation. This paper now demonstrates a robust implementation in a commercial 24 GHz radar tank level gauging system, where an adaptive model-order estimation algorithm is used. The measurements in an industrial tank show a threefold increase of the resolution while maintaining stability. Finally a special set of measurements shows that the selected state-space approach is especially well suited for the resolution of small peaks adjacent to larger echoes. |

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.
