The image registration error

clutter decorreclation and array error have a great influence on the performance of the distributed synthetic aperture radar ground moving target detection.In this paper

an approach on moving target detection and relocation is proposed based on multi-channel and multi-pixel adaptive signal processing in image domain.Firstly

the multi-channel and multi-pixel joint data is equaled to a simple array model.The real steering vector of the moving target can be estimated through the space projection approach on the condition that there is image registration error.The optimal beam forming approach is used to cancel clutter

and at the same time the cross-track velocity of moving target can be determined by searching for the peak value of the cost function and then the moving target can be relocated on the image.The simulation results indicate this method has a good robustness to image registration error

clutter decorrelation and array error

and the detection performance and the estimation accuracy are improved greatly.
