Data fusion allows the elaboration and the evaluation of a situationsynthesized from low level informations provided by different kinds of sensors.The fusion of the collected data will result in fewer and higher levelinformations more easily assessed by a human operator and that will assist himeffectively in his decision process. In this paper we present the suitabilityand the advantages of using a Possibilistic Assumption based Truth MaintenanceSystem (n-ATMS) in a data fusion military application. We first describe theproblem, the needed knowledge representation formalisms and problem solvingparadigms. Then we remind the reader of the basic concepts of ATMSs,Possibilistic Logic and 11-ATMSs. Finally we detail the solution to the givendata fusion problem and conclude with the results and comparison with anon-possibilistic solution.
