sar (synthetic aperture radar) atr (automatic target recognition) algorithm proposed by Lincoln Lab is widely used for its classic mode that is a three-stage framework. The clustering algorithm between prescreener and discriminator of sar atr algorithm is important for the performance of detection algorithm. This paper introduces the common clustering algorithm used in sar atr algorithm and analyzes its disadvantages of clutter disturbance. A morphologic method is proposed to be used before clustering that can delete the isolated pixels and save the pixel blobs in an image. It avoids the disturbance of clutter for clustering. The clustering results of an actual sar image testify that the morphologic method is effective for improving clustering results.
