After the Three Gorges Dam began to function in China in 2003, the water level of the Yangtze River in Three Gorges area raised more than 100 meters. The impact of the man-made reservoir caused by the dam on the surroundings is becoming object of several studies. In this paper we make use of two long term D-InSAR techniques, Quasi-Permanent Scatterer(More)
—An innovative constant false alarm rate (CFAR) algorithm was studied for ship detection using synthetic aperture radar (SAR) images of the sea. Two advances were achieved. An alpha-stable distribution rather than a traditional Weibull or K-distribution was used to model the distribution of sea clutter. The distribution of sea clutter in a SAR image was(More)
This paper describes an improved Constant False Alarm Rate (CFAR) ship detection algorithm in spaceborne synthetic aperture radar (SAR) image based on Alpha-stable distribution model. Typically, the CFAR algorithm uses the Gaussian distribution model to describe statistical characteristics of a SAR image background clutter. However, the Gaussian(More)
In the areas with steep topography and vulnerable geological condition, landslide deformation monitoring is an important task for risk assessment and management. Differential Synthetic-Aperture Radar interferometry (D-InSAR) and Persistent Scatterer Interferometry (PS-InSAR) are two advanced SAR Interferometry techniques for detection, analysis and(More)
1. ABSTRACT Synthetic Aperture Radar (SAR) is an active radar that can provide high resolution images in microwave band under all weather conditions. SAR images have been widely used for fishing vessels detection, ship traffic monitoring and immigration controls [1, 2]. For single channel SAR image, ships can be separated from the sea clutter with an(More)
