GNSS-R Modeling and Retrieval for Soil Moisture

March 28 @ 10:00 am - 11:00 am

Join us at 10:00 AM in MCMR 106 for a candidate presentation from Erik Hodges.

Global Navigation Satellite System Reflectometry (GNSS-R) is a radar technique that takes advantage of existing signals transmitted by navigation satellites such as the GPS. This talk looks at how CYGNSS measurements are used to estimate soil moisture through the development of scattering models and soil moisture products. We’ll also explore a technique for combining multiple CYGNSS soil moisture products using a minimum variance estimator that leads to more accurate soil moisture estimates.

Speaker Bio

Erik Hodges (Member, IEEE) received the B.S. degree in electrical engineering from the University of California at Los Angeles, Los Angeles, CA, USA, in 2019. He is currently pursuing the Ph.D. degree in electrical engineering with the University of Southern California, Los Angeles.,His research interests include global navigation satellite system reflectometry and electromagnetic models for land surfaces.,Mr. Hodges is a member of the Cyclone Global Navigation Satellite System (CYGNSS) Science Team and the IEEE Geoscience and Remote Sensing Society.testing could then be automated through a python script running on the SMU. Currently Erik works for USC as a research assistant in which he has Developed fusion method for combining LIDAR elevation data with traditional elevation models to improve the accuracy of CYGNSS forward model.
