Abstract：With the improving resolution of SAR Images ,the traditional Constant False Alarm(CFAR) algorithm is in-efficient for ship detecting .A new two-stage fast method is proposed for high resolution SAR images in this paper .In the first stage ,the improved algorithm of entropic double-thresholds proposed by Kapur ,Sahoo ,Wong(KSW) is implemented . Then the whole image is divided into three parts ,including target ,suspected target ,and background .In the next stage ,the improved two parameters CFAR algorithm is applied to the pixels in the suspected target area .Combing results of two sta-ges ,ship targets in the image are detected .According to the experiment with real SAR images ,the results show that the method proposed in this paper performs very well in ship detecting .The fast algorithm satisfies the demand of ship detection in high resolution SAR images .
