The main problem of ISAR imaging of ground moving targets (e.g. vehicles) is to gather information about the unknown motion of the target, which should be imaged. This paper describes a possible solution to estimate the translational motion by tracking the centre of reflectivity and to estimate the rotational motion by evaluation of the orientation of the reflectivity distribution. The proposed method will be demonstrated using real data.
