A edge synthesized extraction method of small reflection target for SAR (synthetic aperture radar) image is proposed. A wavelet de-noising method is obtained based SAR image clutter heterogeneity. SAR image segmentation threshold values are calculated based the criteria of smallest error. The interesting target is obtained after several segmentations. The SAR image target edge appears by morphological operation. The validity of this method is tested by real SAR image.
