Method for detection as well as for estimation of velocity and position of moving objects in SAR images

Abstract

The invention relates to a method for the detection as well as speed and position estimation of moving objects in SAR images, comprising the following method steps: - Generating a sequence of consecutive single-look SAR images of the same polarization and from one image to varying look center frequency; - Detection of candidates for moving objects in the single-look SAR images of the sequence by looking for regions with respect to the environment deviant pattern of intensity; - Speed ​​estimation of the detected candidates; - Verification of the detected candidates as moving objects. According to the invention the estimation of one or more speed components of a detected candidate together with the estimation of one or more position components of the candidate, with taking into account the positions of the candidate in the individual single-look SAR images in the sequence being dependent on the to be estimated component cost function is situated which is minimized by means of an optimization method for the mode or parameters to be estimated.
