One of the main difficulties in Inverse Synthetic Aperture Radar imagery of a maneuvering target is the estimation of its motion parameters from the radar data. In this paper we show how the geometric features of a multistatic radar system can be used to obtain both translational and rotational motion with a multilateration approach. While many monostatic approaches in open literature attempt to estimate parameters for a pre-assumed form of motion, our approach aims to be as general as possible. Capabilities and limitations for several implementation techniques of the multilateration method are examined and illustrated in simulations.
