Method and Apparatus for RF Sensing


Motivated by the need for low-cost, non-contact methods to continuously monitor soil moisture at various scales, a new method for sensing soil moisture is being developed. This novel remote sensing technique involves use of a radio frequency (RF) transmitter and receiver to estimate changes in polarization properties of the reflected signal. Laboratory testing demonstrates that soil moisture levels are accurately determined throughout the evaporation cycle. Polarimetric signatures may now be used to monitor acreage from pole-mounted remote sensing devices in a cost-effective manner. Soon, work will begin to place the sensors on drones for periodic measurement of larger areas.
