A Multi-Baseline Phase Unwrapping Algorithm Based on Integrated Processing of Intercept Pre-Filtering and Ambiguity Number Vector Determination

Remote Sensing
Multi-baseline phase unwrapping is a critical procedure in interferometric synthetic aperture radar (InSAR) data processing, and cluster analysis (CA)-based algorithms have become an important research direction in this field.

Spatiotemporal Optimization of Observation Geometry for Wave-Induced Bias in the Kuroshio Region Using the KaDOP Model and Five Years of Hourly ERA5 Reanalysis Data

Remote Sensing
Ocean surface currents (OSCs) are central to upper ocean dynamics and air–sea exchange, yet their retrieval from spaceborne synthetic aperture radar (SAR) is limited by wave-induced bias (WB).

Sea-Surface Current Vector Retrieval Using Squinted Multiaperture ATI-SAR (Sq-MA-ATI)

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Ocean surface-current vector retrieval using conventional along-track interferometric synthetic aperture radar remains challenging because, under broadside viewing, the line-of-sight velocity has little along-track projection and a 2-D current vector ...
