Microwave radar for detection of resin defects in Pinus elliottii Engelm var elliottii

Abstract Surface penetrating microwave radar is identified as a low-cost, reliable, portable, and safe means of detecting resin defects in plantation-grown pine logs. This new method of non-destructively testing logs has the potential to be applied at several intervention points in the value chain, including on standing trees, fallen stems, and merchandised logs either in the forest or in the mill. Results clearly distinguish resin-affected logs from unaffected logs, even in logs of high moisture content.
