The invention relates to processes which make it possible to track moving craft logged by a set of sensors and to reconstruct their course. It consists in meshing (101) the space in which these moving craft may be sited and in distributing weights (102) over this mesh, which are determined from the measurements by the sensors. These weights then make it possible to determine the most probable paths (103). To do this, the movements of the targets are modelled with the aid of hidden Markov chains and the paths are constructed with the aid of the Viterbi algorithm. It makes it possible to undertake such tracking and such course reconstruction with no prior assumption or modelling. <IMAGE>
