Reported herein is the estimation of the residual error of the reflectivity displacement method (RDM) and the dependence of RDM on terrain characteristics. The RDM is a method to be implemented on airborne synthetic aperture radars (SAR). It extracts the motion of the aircraft from the radar backscatter signal, allowing for motion compensation without using an inertial navigation system. An extended error analysis of this method and its dependence on the terrain type and contrast is performed. Results proving the estimated performance are shown.
