چکیده

SAR (Synthetic Aperture Radar) images with very high resolution (till 1 meter) are now provided by new powerful sensors but their analysis, interpretation and classification are very hard when urban areas are under study. In this paper the high resolution in SAR images of built-up areas is faced with a model-based approach allowing detection and correct interpretation of 1 meter geometries.

Very High Resolution Parametric and Non- Parametric Sartomography Methods for Monitoring Urban Areas Structures

Synthetic Aperture Radar (SAR) is the only way to evaluate deformation of the Earth’s surface from space on the order of centimeters and millimeters due to its coherent nature and short wavelengths. Hence, by this means the long term risk monitoring and security are performed as precisely as possible. Traditional SAR imaging delivers a projection of the 3-D object to the two dimensional (2-D) a...

Introducing An Efficient Set of High Spatial Resolution Images of Urban Areas to Evaluate Building Detection Algorithms

The present work aims to introduce an efficient set of high spatial resolution (HSR) images in order to more fairly evaluate building detection algorithms. The introduced images are chosen from two recent HSR sensors (QuickBird and GeoEye-1) and based on several challenges of urban areas encountered in building detection such as diversity in building density, building dissociation, building sha...

The Extended Sub-look Analysis In Polarimetric SAR Data For Ship Detection

The monitoring of maritime areas with remote sensing is essential for security reasons and also for the conservation of environment. The synthetic aperture radar (SAR) can play an important role in this matter by considering the possibility of acquiring high-resolution images at nighttime and under cloud cover. Recently, the new approaches based on the sub-look analysis for preserving the infor...

Assessment of Automatic Structure Detection through Variance Parameters in High Resolution Sar Images of Urban Areas

In this paper we aim at describing a method to extract information about urban structure on high resolution Synthetic Aperture Radar (SAR) images. The extraction of useful information from SAR images is a difficult task, due to the presence of the characteristic speckle noise but also for the geometrical and physical nature of man made areas. The technique proposed in this paper was used to imp...

Sar Simulation Based Change Detection with High-resolution Sar Images in Urban Environments

Combined processing using different sensor types, i.e. for applications like change detection, requires a good geo-referencing. Furthermore the individual sensor properties have to be taken into account. SAR systems are side-looking and run-time systems. They suffer from occlusions and ambiguities especially in urban areas. Additionally layover and shadow effects disturb the geo-referencing of ...
