Near-Real-Time InSAR Phase Estimation for Large-Scale Surface Displacement Monitoring
Scott Staniewicz, Sara Mirzaee, Heresh Fattahi +12
Operational near-real-time monitoring of Earth's surface deformation using Interferometric Synthetic Aperture Radar (InSAR) requires processing algorithms that efficiently incorpor…
Modifying Range-Doppler geometry frameworks to process Spotlight SAR imagery in Polar Format
Piyush S. Agram
We present a simple method to enable processing of Spotlight Synthetic Aperture Radar (SAR) imagery distributed in Polar Format (PFA) using standard Range-Doppler (RDA) geometry al…
Deformation monitoring with Sentinel-1 Wave mode data
Piyush S. Agram, Matthew T. Calef, Kelly M. Olsen +2
We describe the salient characteristics of Sentinel-1 wave (WV) mode vignettes. We describe our approach for working with WV mode data that enables vignette-based data access and p…
Merging Point Data for InSAR Deformation Processing
Matthew T. Calef, Kelly M. Olsen, Piyush S. Agram
Given a collection of points , which is partitioned into overlapping subsets , and approximate data associated with t…
