Abstract :
Ship detection is an important section of Synthetic Aperture Radar´s marine applications. Through analyzing the distribution characteristics of ship targets and speckle, a novel ship detection method based on NSCT and ACO is proposed for SAR image processing. First, apply NSCT adaptive threshold method to de-noise the SAR images, then detect the edges by ACO, last ship targets can be precisely detected. Simulating results indicate that this method can not only pickup contour information of ship objects in complex speckle efficiently, but also keep ships structure well, show ideal antijamming competence, guarantee the detection accuracy.
