| Abstract | The first-order bistatic high-frequency radar cross-section of ocean surface is derived for the case of a fixed receiver and a floating, but tethered, transmitter. A general expression for the bistatically received first-order electric field is obtained from earlier work based on fixed antennas. A small displacement caused by the platform motion is added in the source term to modify the stationary antenna model. Based on the assumption that the ocean surface can be described as a Fourier series with coefficients being random variables, the first-order bistatic radar cross-section is derived. The effect of the platform motion is found to produce a sum of Bessel functions in the final cross-section result, varying in order from zero to infinity. Under appropriately specified conditions, the bistatic model with antenna motion is verified to reduce to the monostatic model with antenna motion and the bistatic stationary model, respectively. Assuming a simple model in which the platform motion is caused by the dominant ocean wave, simulations are made to show the effect of platform motion on the radar cross-section under a variety of sea states and operating frequencies. |

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.
