Irrigated Grassland Monitoring Using a Time Series of TerraSAR-X and COSMO-SkyMed X-Band SAR Data
The objective of this study was to analyze the sensitivity of radar signals in the X-band in irrigated grassland conditions. The backscattered radar signals were analyzed according to soil moisture and vegetation parameters using linear regression models. A time series of radar (TerraSAR-X and COSMO-SkyMed) and optical (SPOT and LANDSAT) images was acquired at a high temporal frequency in 2013 ...
متن کاملThe Intercomparison of X-Band SAR Images from COSMO-SkyMed and TerraSAR-X Satellites: Case Studies
The analysis of experimental data collected by X-band SAR of COSMO-SkyMed (CSK®) and TerraSAR-X (TSX) images on the same surface types has shown significant differences in the signal level of the two sensors. In order to investigate the possibility of combining data from the two instruments, a study was carried out by comparing images collected with similar orbital and sensor parameters (e.g., ...
متن کاملPotential of X-Band TerraSAR-X and COSMO-SkyMed SAR Data for the Assessment of Physical Soil Parameters
The aim of this paper is to analyze the potential of X-band SAR measurements (COSMO-SkyMed and TerraSAR-X) made over bare soils for the estimation of soil moisture and surface geometry parameters at a semi-arid site in Tunisia (North Africa). Radar signals acquired with different configurations (HH and VV polarizations, incidence angles of 26° and 36°) are statistically compared with ground mea...
متن کاملAnalyzing Terrasar-x and Cosmo-skymed High-resolution Sar Data of Urban Areas
The new high-resolution synthetic aperture radar (SAR) satellite systems offer new possibilities for urban remote sensing. COSMOSkyMed and TerraSAR-X operate in X-band and both can deliver data with a spatial resolution of up to one meter. High-resolution SAR data is particularly useful for post-disaster damage assessment and monitoring, because SAR systems operate (almost) weather independent....
متن کاملA Study of the Rpc Model of Terrasar-x and Cosmo-skymed Sar Imagery
The rational polynomial coefficient (RPC) model has recently raised considerable interest in the photogrammetry and remote sensing community. This model is a generalized sensor model that is capable of achieving high approximation accuracy. Unfortunately, in all previous literature, the computation of the parameters of the RPC model depends on initial values for the parameters. In this paper, a...
