一种 SAR 图像舰船目标快速检测方法
A Fast Method for Ship Detection in SAR Imagery
摘要
Abstract
Automatic ship detection plays an important role in the ocean surveillance application of SAR imagery. As the increasing of SAR imaging ability and image resolution, the conventional CFAR can't meet the requirement of automatic ship detection. For the ship detection in medium and high resolution SAR imagery, a fast method for ship detection from SAR imagery based on pixel excision in G?distributed sea clutter is proposed in this paper. The method excises clutter pixels with a threshold determined by the appearance frequency first, then reduces resolution by the sampling procedure and carries through automatic ship detection finally. Detection results on JPL/NASA A1RSAR data illustrate the method can reduce the number of false alarm and improve the calculation efficiency remarkably.关键词
