Detection of Ships and Ship Wakes in Spaceborne SAR Imagery

摘要: 研究了星载SAR图像中船舶目标及其航迹的检测提取方法。通过扩展分形特征检测船舶目标,在目标周围运用局部Radon变换检测航迹。实验结果表明,本文方法对于静止和运动船舶目标的检测都具有较强的鲁棒性。

Abstract: This paper discusses the detection of ships and ship wakes, and proposes a scheme with a series of steps for combined detection.The extended fractal (EF) feature is a detection statistic, which can greatly enhance the detection probability.The experiments show that the EF features provide improved detections performance.The Radon transform is commonly used in algorithms for detecting linear features in imagery. The results demonstrate the ability of this approach to successfully detect the linear components of ship wakes visible in SAR imagery.
