Evaluation of Experimental Data From the Gains Balloon GPS Surface Reflection Instrument

摘要

In this paper, we have reported the current readiness status of the GPS Surface Reflection Instrument for the GAINS balloon mission. We have discussed the mission background, highlighting the evidence for the usefulness of the reflected GPS signal for remote sensing. That section also cited the potential of utilizing the reflected signal over terrestrial areas for measurement of the ground soil moisture. We then discussed the capabilities of the GSRI as it has been configured for the GAINS balloon mission. The instrument capabilities of elevation correction and its multiple modes of data collection provide a versatile basis for an initial exploration of the potential for utilization of the terrestrial reflected GPS signal. We then provided an overview of the data collection methodology for creating the data set, and the approach that is to be used for the initial analysis of that data set. As a result of the initial analysis, additional approaches to analyzing the data may be suggested. These approaches will be developed and evaluated as the research proceeds.
