| Abstract | This paper considers the problem of tracking a target - which might or might not exist - from a platform whose position is not known perfectly and might contain substantial time dependencies. Most single and multi-target tracking algorithms implicitly or explicitly assume that the location of the sensor platform system is known perfectly. However, in practice the location of sensing platforms is often estimated, usually by fusing a set of sensor measurements from different sources. As a result, the error in the platform estimates could be significant and time correlated. These difficulties are compounded in single and multi-target tracking problems when the existence of a target is not guaranteed. In this paper, we consider the problem of tracking at most a single target from a poorly-localized UAV. We develop a formulation of the Bernoulli filter which incorporates both the target state and the state of the platform. However, because the dimension of the state is relatively large, we develop a suboptimal algorithm which, through neglecting the use of track information to improve the quality of the platform estimate, scales in a manner very similar to that of a conventional Bernoulli filter. The implementations of the different algorithms are tested in a simulation scenario of a UAV performing safety monitoring of a convoy. |

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.
