A Robust Interferometric Phase Extraction Algorithm With Hierarchical PS Sequence Construction for GNSS-Based InBSAR
Global Navigation Satellite System (GNSS)-based interferometric bistatic synthetic aperture radar (InBSAR) enables deformation monitoring using on-orbit navigation satellites as transmitters and a ground-fixed receiver. However, the low spatial resolution, poor signal-to-noise ratio (SNR), and inherent asymmetric bista...
