HYBRID GEOMETRIC CALIBRATION METHOD FOR MULTI-PLATFORM SPACEBORNE SAR IMAGE WITH SPARSE GCPS
SAR image geometric calibration R-D model multi-platform TerraSAR-X TanDEM-X Gaofen-3
2018/5/15
Geometric calibration is able to provide high-accuracy geometric coordinates of spaceborne SAR image through accurate geometric parameters in the Range-Doppler model by ground control points (GCPs). H...
A MATCHING METHOD TO REDUCE THE INFLUENCE OF SAR GEOMETRIC DEFORMATION
SAR image image matching SURF SNCC geometrical deformations
2018/5/14
There are large geometrical deformations in SAR image, including foreshortening, layover, shade，which leads to SAR Image matching with low accuracy. Especially in complex terrain area, the control poi...
A RAPID METHOD FOR WATER TARGET EXTRACTION IN SAR IMAGE
Synthetic Aperture Radar Imagery Water Target Automatic Recognition Grey Morphology Nonlinear Filter
2015/12/23
For the inherent speckles in SAR imagery, the processing of object extraction becomes more difficult. Using the traditional target extraction arithmetic for optical imagery, we can not get ideal resul...
Calibrating Cerrado Physiognomies Using Sar and Optical Images in Brazil
JERS-1/SAR TERRA-MODIS CERRADO PHYSIOGNOMIES NDVI
2015/7/7
The objective of this study is to evaluate the potential use of L-band SAR images, comparing to optical images, to separate the
physiognomic gradient of the Cerrado biome. The field data come from a ...
USE OF GEOSTATISTICS TO INTEGRATE INTERFEROMETRIC SAR DATA WITH LEVELING MEASUREMENTS OF LAND SUBSIDENCE
GEOSTATISTICS INTERFEROMETRIC SAR DATA LEVELING MEASUREMENTS LAND SUBSIDENCE
2015/6/1
D-InSAR data of ground surface deformation have uncertainty caused by several sources associated with image acquisitions and data processing. In this study, these data are modeled as the sum of a tren...
SAR-Based 3D Reconstruction of Complex Urban Environments
SAR SAR simulation building reconstruction city model semi-automation
2015/5/26
Within the paper the applicability of SAR imagery for 3D reconstruction of urban areas will be discussed. Since data collection for
this purpose is usually based on stereo imagery or dense point clo...
AUTOMATIC MAPPING OF GLACIER BASED ON SAR IMAGERY BY BENEFITS OF FREELY OPTICAL AND THERMAL DATA
Glacier Surface Area SAR Optical data Thermal data
2015/4/1
For many research applications like water resources evaluation, determination of glacier specific changes, and for calculation of the past and future contribution of glaciers to sea-level change, para...
EXTRACTING BUILT-UP AREAS FROM MULTITEMPORAL INTERFEROMETRIC SAR IMAGES
Land Use Urban SAR Segmentation Classification
2015/3/24
Automatic extraction of built-up areas from a multitemporal interferometric ERS-1/2 Tandem SAR dataset was studied. The image
data were segmented into homogeneous regions and the regions were classi...
MONITORING OF RICE-PLANTED AREAS USING SPACE-BORNE SAR DATA
