| Abstract | We propose a scheme for bistatic radar that uses a three-dimensional chaotic system to generate a wideband signal that is replicated at the receiver to extract high resolution information from targets. The setup for the bistatic radar includes a drive oscillator at the transmitter and a response oscillator at the receiver. The challenge for this setup is synchronizing the response oscillator of the radar receiver utilizing a scaled version of the transmitted signal that is a function of one drive oscillator state variable where the scaling factor accounts for antenna gain, system losses, and space propagation. Since the scaling factor is not known a priori, the response oscillator must be able to accept the scaled version of the state variable as an input. Thus, we improve upon a generalized projective synchronization technique that introduces a controller variable and a controller parameter into the Lorenz system and show that the synchronization is achievable. We verify through simulations that, once synchronization is achieved, the short-time correlation of the driver and response state variables is high and that this correlation is consistent over long periods of time. |

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.
