Selected Projects
DroneSAR — UAV-Based S-Band Synthetic Aperture Radar
Lead development of a small-UAV fully polarimetric S-band SAR system, including system integration, calibration, SAR processing, interference filtering, motion compensation, georeferencing, and field campaigns.
Soil Moisture & Biomass Retrieval
Development of retrieval algorithms using calibrated radar data and in-situ measurements, with current work extending toward uncertainty-aware retrieval and data assimilation.
GNSS-R Synthetic Aperture Radar
Concept and algorithm development for SAR processing using GNSS reflectometry signals, including satellite-position solutions and phased-array processing for directional ambiguity.
CYGNSS Soil Moisture Data Assimilation
Development of Ensemble Kalman Filter workflows for assimilating GNSS-R soil-moisture products into a hydrologic model for root-zone soil-moisture estimation.
SNOOPI — P-Band Signals of Opportunity
Algorithm development for an in-space demonstration of Earth remote sensing using P-band communication signals of opportunity.
