X-SAR Data Quality - The Results of two Missions
نویسندگان
چکیده
– In April and October 1994 X–SAR was flown on a Space Shuttle as a component of the 3 frequency Space Radar Laboratory SIR–C/X–SAR. While both missions were scheduled to investigate seasonal changes, 3 days of the October mission were optimized for SAR interferometry. At DLR all X–SAR data are analyzed and processed to precision images. During the analysis raw data parameters like chirp phase and amplitude stability, raw data statistics, system noise and Doppler centroid frequency are investigated. The paper summarizes and compares those parameters of both missions. During the second mission interferograms were generated from X–SAR data. The paper presents the effects of Doppler centroid frequency variations on the suitability of X–SAR data for two–pass interferometry.

Validation of S-band data performance for future spaceborne SAR missions
Most of the SAR missions of the latest years presented sensors working in X-band (like in the TerraSAR-X and Cosmo-SkyMed missions). Today new SAR missions, working at alternative frequencies like S-band, are under planning/design and will be launched in the upcoming years. In addition, full polarimetry is likely to be implemented in some of those missions. This is the case of the UK sensor Nov...
متن کاملSAR interferometry analyses and experiments with COSMO-SkyMed
The new X-band SAR missions provide SAR images characterized by a much higher resolution, opening new possibilities for SAR interferometry. Thanks to the high resolution it is expected to find a larger number of coherent points or persistent scatterers per unit area, resulting in more detailed and accurate measurements by means of SAR differential interferometry techniques. Among the other char...

متن کاملAssessment of radar interferometry performance for ground subsidence monitoring due to underground mining
This paper describes the results from the recently launched SAR satellites for the purpose of subsidence monitoring over underground coal mine sites in the state of New South Wales, Australia, using differential interferometric synthetic aperture radar (DInSAR) technique. The quality of the mine subsidence monitoring results is mainly constrained by noise due to the spatial and temporal decorre...
