نویسندگان
چکیده
The long-term goal of this project is the establishment of receiving, processing, and interpretation capabilities for spaceborne along-track interferometric synthetic aperture radar (along-track InSAR, ATI) data at the University of Miami's Center for Southeastern Tropical Advanced Remote Sensing (CSTARS) for high-resolution surface current field mapping with special emphasis on applications in estuarine environments and rivers.

Demonstration of Current Measurements from Space by Along-Track SAR Interferometry with SRTM Data
We present one of the first studies in which interferometric synthetic aperture radar (InSAR) data from the Shuttle Radar Topography Mission (SRTM) are analyzed with regard to the detectability of ocean surface current variations. The InSAR system of SRTM was designed for high-resolution topographic mapping, using two SAR antennas on a Space Shuttle with a cross-track separation of 60 m. For te...
متن کاملTime-Domain Simulation of Along-Track Interferometric SAR for Moving Ocean Surfaces
A time-domain simulation of along-track interferometric synthetic aperture radar (AT-InSAR) has been developed to support ocean observations. The simulation is in the time domain and based on Bragg scattering to be applicable for moving ocean surfaces. The time-domain simulation is suitable for examining velocities of moving objects. The simulation obtains the time series of microwave backscatt...
متن کاملCold‐regions river flow observed from space
[1] Knowledge of water‐surface velocities in rivers is useful for understanding a wide range of lotic processes and systems, such as water and ice fluxes and forces, mixing, solute and sediment transport, bed and bank stability, aquatic and riparian ecology, and extreme hydrologic events. In cold regions, river‐ice break up and the associated downstream transport of ice debris is often the most...

Results from multiple systems ope...
متن کاملOptimal Baseline Design and Error Compensation for Bistatic Spaceborne InSAR
s: Bistatic SAR systems as opposed to monostatic SAR offer some degrees of freedom in choosing transmitter and receiver separately. In this paper, the spatial baseline in bistatic spaceborne InSAR and the requirements of optimal baseline are analyzed in many aspects. An equation to determine the optimal spatial baseline is derived, and one method to estimate and correct the baseline error cause...
