A Target Detection Method Based on Multi-aperture SAR Images

WANG Changcheng1 LIAO Mingsheng1(1 State Key Laboratory for Information Engineering in Surveying,Mapping and Remote Sensing,Wuhan University,129 Luoyu Road,Wuhan 430079,China)  
A target detection method based on multi-aperture SAR images is proposed.With this method the magnitude and the phase characteristics of SAR images were jointly used to distinguish artificial target from clutter.A number of sub-aperture images are generated from SAR image.As the energy of artificial target usually masses in partial range of azimuth angle,the local correlation between the sub-aperture images which are corresponding to the partial range of azimuth angle is strong in the presence of targets.So,the use of the coherence between these sub-aperture images is proposed for target detection.Experimental results demonstrate that the proposed method enhances the detection rate and reduces the false alarm rate effectively.
