Cranberry Field Measurement Data - Central WI Fall 2017

We collected experimental fielddata with a prototype open-ended waveguide sensor (WR975) operatingbetween 600 MHz - 1300 MHz.With our prototype sensor we collected reflection coefficientmeasurements at a total of 50 unique 1-ft^2 sites across two separateestablished cranberry beds in central Wisconsin.The sensor was placed directly on top ofcranberry-crop bed canopies, and we obtained 12 independentreflection coefficient measurements (each defined as one S11sweep across frequency) at each 1-ft^2 site by randomly rotatingand/or translating the sensor aperture above each site.After the12 measurements at each 1-ft^2 site were logged, we harvestedall of the cranberries in the canopy volume bounded by the1-ft^2marker.The total mass of the harvested cranberries in each 1-ft^2 site is the ground-truth yield.

本研究采用工作于600 MHz至1300 MHz频段的原型开口波导传感器（WR975）采集野外实验数据。依托该原型传感器，我们在威斯康星州中部两处已定植的蔓越莓种植床内，共计采集了50个互不重复的1平方英尺采样点的反射系数（reflection coefficient）测量数据。将传感器直接放置于蔓越莓种植床冠层表面，通过在每个采样点上方随机旋转或平移传感器孔径，我们在每个1平方英尺采样点上获取了12次独立反射系数测量，每次测量对应一次全频段S11扫描。完成每个采样点的12次测量记录后，我们采收了以该1平方英尺标记为边界的冠层体积内的全部蔓越莓。各采样点内采收蔓越莓的总质量即为该点位的地面真值产量。
