Abstract (AI)
The authors have utilized a set of Seasat synthetic aperture radar (SAR) data that were obtained in nearly repeat ground-track orbits to demonstrate the performance of spaceborne interferometric SAR (INSAR) systems. An assessment of the topography measurement capability is presented. A phase measurement error model is described and compared with the data obtained at various baseline separations and signal-to-noise ratios. Finally, the implications of these results on future spaceborne INSAR design are discussed.>
Key Findings
1
A phase-measurement error model was developed and compared against observations across different baseline separations and signal-to-noise ratios.
2
Seasat SAR data from nearly repeat ground-track orbits were used to demonstrate the performance of multibaseline spaceborne interferometric SAR systems.
3
The results were used to derive implications for the design of future spaceborne INSAR systems.
4
The study assessed the capability of spaceborne INSAR to measure surface topography.
