As an essential tool for the study of the Earth microwave remote sensing can provide valuable information regarding the state of the oceans, polar regions, and vegetated areas. I am currently involved in interdisicplinary research and development of a variety of advanced microwave remote sensing instruments, techniques, and applications, including the development of mesoscale models of oceanic winds for use in model-based wind retrieval (estimation) algorithms from scatterometer data, resolution enhancement algorithms, sampling theory, cryosphere studies, as well as innovative SAR and scatterometer systems.
Selected specific research topics include:
Spaceborne wind scatterometry (radar remote sensing of oceanic winds)
Scatterometer model functions
Rain modeling and measurement
Remote sensing of polar ice
Remote sensing of tropical and subtropical vegetaion
Synthetic Aperture Radar (SAR)
Resolution enhancement and reconstruction algorithms (e.g., SIR)
