| Abstract | This paper deals with the reduction of the ambiguity peaks that appear in the Cross Ambiguity Function used in a passive radar system, which uses DVB-T signals as Illuminator of Opportunity. Three methods are proposed, consisting in replacing the elements that are responsible of the ambiguity peaks, by other elements that do not give rise to periodic components. Ideal 64-QAM symbols, zero power components, and random segments with mean power equal to the acquired signal power, are used for this purpose. The obtained results show that a significant reduction of the ambiguity peaks is obtained, but with an undesired reduction in detection capabilities, due to the decrement in the main peak to pedestal level ratio. |

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.
