Abstract | A method is introduced in this paper to identify coherent scatterers (CS) with high spectral correlation among sublook SAR images. Using this method, the CSs can be identified in single SAR image. And the multi-reference radar interferometry is proposed to monitor urban subsidence with the candidate CSs. An experiment was conducted utilizing eight ALOS PALSAR SAR images over Zhengzhou urban area during the year of 2007–2010. The experiment has demonstrated that the identified CSs have large interferometric coherence and small amplitude deviation, which indicates the phase are stable during the time span. The displacement mean square error is 7.6 mm/a comparison with ground leveling data, which demonstrates that the proposed algorithm is reliable. |

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.
