| Abstract | Techniques devised to correct aliased Doppler velocity PPI maps obtained from meteorological radars seem to have not accounted for the possible presence of extended areas of ground clutter and/or practical absence of signal due to beam screening. This is a severe limit for radars operating in hilly terrain. Dealiasing methods are necessarily based on hypotheses of continuity of the radial velocity field, which are quite hard to exploit when such a field is corrupted by ground clutter, or even void of data over relatively waste areas. The authors discuss this topic, first showing some drawbacks that a classical dealiasing technique undergoes when utilized in such a context. Data utilized are those gathered by a dual polarization Doppler weather radar sited in Tuscany, in a quite orographically complex environment. After that, they describe a modified algorithm that overcomes the limitations of the original technique, and show that the proposed modifications are useful to make the algorithm work correctly even under severe clutter/beam screening conditions. |

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.
