| Abstract | This paper addresses a frame-overlapped zoom-FFT method applied to pulse Doppler (PD) radar echo spectrum analysis. The method can achieve high resolution of local spectrum, and improve the gain of coherent integration, so it can enhance the detection probability and the precision of parameter estimation for poor echo signal. Firstly this paper introduces the principal of frame-overlapped zoom-FFT. Then it addresses the parameter design criterions in high pulse repeat frequency (HPRF) PD radar application. Furthermore based on analyzing the effects on incoherent integration and target detection due to frame overlap, it illustrates the parameter design process by an example of PD radar spectrum analysis application and gives the comparison of overlap processing and no-overlap processing. Finally, a real-time spectrum analysis system implementation adopting the frame-overlapped zoom-FFT method is proposed |

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.
