Why is TRU called a “Virtual Excavator”?
Radar waveforms are automatically pulsed and subsurface soil reflections recorded for every 0.2 in (5 mm) of movement throughout a subsurface roots scan line. Whenever a root is detected, its location and depth is determined. A 2D planar image, created by the off-line TreeWin™ software, shows the same depth view that would be made by a backhoe or a hyper-sonic air excavator; hence, a “virtual trench “.
