Building extraction is an important task for SAR applications in many fields, such as urban planning, population distribution, and environment evaluation. In this paper, we focus on high-rise buildings in complex urban scenarios. The specific characteristics of high-rise building in high resolution (HR) SAR images are analyzed firstly. In particular, we explore the contextual information of bright...
Target recognition in high-resolution synthetic aperture radar (SAR) images is a challenging task. In this letter, a novel geometrical-based SAR image simulator is proposed to assist target recognition. Specifically, in addition to the using of Lamberitian-specular mixed model for single-bounce simulation, we propose a dihedral corner model for double-bounce simulation, which allows directly retrieving...
Cylinder tanks appear as arcs in SAR image. It is found the radius of some arcs is bigger than the radius of the tank. To analysis this phenomenon, combining the scattering theory and the principle of SAR, a novel prediction model about the SAR image of cylinder tanks, including the tanks with fixed top and floating top, is proposed. Analysis on details of the SAR image of the tanks is provided by...
