Abstract | It is well known, that the backscattering radiometric accuracy of radar scatterometers for ocean surface wind and precipitation measurements is decided by the signal-to-noise ratio and number of independent samples for non-coherent average. For sea wind scatterometers and meteorological radars, pulse compression can be employed to improve the range resolution and increase the number of independent numbers. But for airborne and spaceborne scatterometers, the peak power of the transmitter and the pulse length are usually decided by the platform capability, orbit parameter and observation geometry. As a result, compromise and trade-off between the signal-to-noise ratio (SNR) for measurement of each resolution cell and the total number of independent samples of each pulse are usually required. In this paper, based on the radiometric accuracy model, an optimization scheme for design of the independent samples numbers and the corresponding system bandwidth are presented. Based on the presented optimization scheme, the bandwidth of a Ku-band rotating fan-beam radar scatterometer for sea surface wind measurement is design. Simulation validates the optimization and design results. |

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.
