摘要
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: Generation of a sequence of temporally successive single-look SAR images and a same polarization of image varying image to 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, one dependent on the to be estimated component cost function is set taking into account the positions of the candidate in the individual single-look SAR images in the sequence which is minimized by means of an optimization method for the or the parameters to be estimated.
