Research Summary

Dr. Garrison's research focuses on developing new techniques for Earth remote sensing in microwave frequencies using signals of opportunity. He is presently conducting several projects to improve the sensing of ocean winds, ocean salinity, atmospheric water vapor and seismic events. Recently he has proposed methods for measuring soil moisture at depths of several decimeters and is conducting field experiments to test this approach. The size, weight and power of instruments based upon these principles are an order of magnitude smaller than the present state of art instruments, enabling them to be deployed on small ??nanosatellites?? or unmanned aerial vehicles (UAVs).
