Abstract
The disclosure concerns a method for determining a change in position and orientation of an object using data from a synthetic aperture radar (SAR) with the following steps: acquiring a radar image containing the object; dividing the radar image into at least two subimages; acquiring short radar information comprising a first reflected pulse, which has been recorded by the radar and/or a quantity derived therefrom, the first reflected pulse having information about image data of the radar image; for the short radar information, performing an autofocus method which determines a change in distance for each of the at least two subimages; and determining the change in position and orientation of the object given for each point of the object by the respective change in distance of the corresponding subimage.
