| Abstract | Surveillance systems, both based on radio frequencies (Radio Detection and Ranging: radar) and optical signals (Light Detection and Ranging: lidar), are evolving toward multiband multifunctional systems that are putting electronic technologies under pressure. Thanks to its intrinsic high stability, ultra-wide bandwidth, low loss propagation, EMI insensitivity, and high frequency of the optical carrier, photonics can be exploited not only for optical systems but also for facing these new requirements in RF systems. In fact, microwave photonics technologies play a crucial role in the generation of very stable multi-band radiofrequency (RF) sources, and in very precise and wideband RF signal detection and digitization, guaranteeing a higher level of flexibility and reconfigurability, and the complete software-defined configuration of radar systems. At the same time they allow to implement multifrequency lidars able to synthesize tunable RFs on optical carriers, for the exploitation of RF radar techniques in lidar systems. Moreover solutions based on integrated photonic circuits allow for a reduction of power consumption and footprint thanks to the subsystems' implementation on a chip. |

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.
