Cranberry Field Measurement Data - Central WI Fall 2017
We collected experimental field data with a prototype open-ended waveguide sensor (WR975) operating between 600 MHz - 1300 MHz. With our prototype sensor we collected reflection coefficient measurements at a total of 50 unique 1-ft^2 sites across two separate established cranberry beds in central Wisconsin. The sensor was placed directly on top of cranberry-crop bed canopies, and we obtained 12 independent reflection coefficient measurements (each defined as one S11 sweep across frequency) at each 1-ft^2 site by randomly rotating and/or translating the sensor aperture above each site. After the 12 measurements at each 1-ft^2 site were logged, we harvested all of the cranberries in the canopy volume bounded by the 1-ft^2 marker. The total mass of the harvested cranberries in each 1-ft^2 site is the ground-truth yield.
