| Abstract | Wuhan ionospheric oblique backscattering sounding system (WIOBSS) is a low-power high-frequency monostatic radar used for ionospheric sensing and aircraft detection. In this study, a novel waveform combining the pseudo-random binary phase coding (PRBPC) and the chirp modulation is proposed for this radar. Furthermore, in terms of the radar waveform requirements, four subclasses of this waveform are theoretically compared to determine which one of them is most suitable for WIOBSS, including the inter-pulse PRBPC waveform where the width of the subpulse is equal to the chirp duration, the inter-pulse PRBPC waveform where the period of the coding sequence is equal to the chirp duration, the intra-pulse PRBPC waveform where the width of the subpulse is equal to the chirp duration, and the intra-pulse PRBPC waveform where the period of the coding sequence is equal to the chirp duration. The radar waveform requirements, the ambiguity function analysis, and the performance comparison of aforementioned waveforms are described. The analysis results show that the inter-pulse PRBPC waveform where the period of the coding sequence is equal to the chirp duration has the best performance, and can achieve higher range resolution, larger signal processing gain, and better Doppler tolerance than the conventional binary phase coded waveforms. |

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.
