| Abstract | To increase the mobility of an unmanned ground vehicle, this study describes new approach to detect targets in front of mono-static terrain imaging radar (TIR), which is a prototypical ground-based forward looking radar. Since the TIR employs a mono-static configuration and a real aperture antenna array, the conventional back-projection method is very useful in spite of its poor processing time. However, it is difficult to employ another method because the TIR is an ultra-wide-band type of radar and employs a dechirp-on-receive process. To overcome these difficulties, a new approach based on scaling function processing is proposed in this study. This scaling function is based on a spectral analysis approach and the proposed method conducts range cell migration compensation, secondary range compression and azimuth compression using this scaling function. In this study, the complete derivation of the proposed method is presented. A very useful formulation for a dechirped mono-static radar signal in the range Doppler domain is also proposed, in which the signal is expressed by the scaling function. The results of simulations and field tests are demonstrated to show the performance and validity of the proposed method. |

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.
