In this paper, the potential of using free-of-charge Sentinel-1 Synthetic Aperture Radar (SAR) imagery for land cover mapping in urban areas is investigated. To this aim, we use dual-pol (VV+VH) Inter...
The Emilia Romagna Region (N-E Italy) and in particular the Adriatic Sea coastline of Ravenna, is affected by a noticeable subsidence that started in the 1950s, when the exploitation of on and off-sho...
This paper proposed a method of unsupervised classification of polarimetric SAR data based on image clustering and H/A/a decomposition. Fully polarimetric L band data collected by ALOS PALSAR system w...
The world is experiencing a rapid rate of urban expansion mainly caused by the rapid population growth. Remote sensing images can give patterns of urban growth, but urban areas are difficult to map be...
State-of-the-art airborne SAR sensors provide spatial resolution on the order of a decimetre. In such data, many features of urban objects can be identified, which were beyond the scope of radar remot...
Within the paper the automatic matching of existing GIS data to airborne SAR scenes for georeferencing is discussed. For this purpose simulated SAR images are generated based on the available GIS obje...
State-of-the-art airborne SAR sensors provide spatial resolution on the order of a decimetre. In such data, many features of urban objects can be identified, which were beyond the scope of radar remot...
The aim of the here presented research was to investigate the potential of two-pass differential InSAR, and advanced DInSAR techniques, such as Small Baseline Subset (SBAS) and Persistent Scatterers...
Over 15 million people were officially considered as refugees in the year 2012 and another 28 million as internally displaced people (IDPs). Natural disasters, climatic and environmental changes, vi...
Algorithmic variations to the glacier motion estimation from differential SAR interferometry are discussed in the present paper. Two efficient albeit relatively simple algorithms for modelling glaci...
In the present study, quantification of spatial and temporal changes has been carried out between Indian Antarctic Research station Bharati and Amery ice shelf by monitoring the ice margins using RISA...
Various urban targets (land use) from Ahmedabad city were chosen, followed by generation of polarimetric signatures for each target using the developed tool. These polarimetric signatures were then st...
This paper presents the first demonstration of high precision very high resolution tomographic SAR inversion with the assistance of TanDEM-X data. The data quality of TerraSAR-X and TanDEM-X is invest...
This paper analyzes the potentials offered by the TanDEM-X mission for the generation of urban DEMs. Operationally acquired urban Raw DEMs are validated using as reference a LiDAR DEM. The approach us...
配准作为干涉处理过程中的重要一步,其精度直接影响后续的处理。机载重复轨道干涉数据,由于飞行的姿态不一致,导致影像间产生较大的相对变形,常规的方法无法对整幅影像进行配准。本文结合SIFT匹配算法的稳健性和解析搜索配准算法高精度的优点,利用飞行轨道间的关系和统计分析剔除错误的匹配,提出了一种针对机载重复轨道干涉数据的配准方法,有效解决了机载重复轨道干涉数据的配准问题。首先利用SIFT匹配算法提取一定数...
