TRU System and Software

SHARE

The patented TRU™ (Tree Radar Unit) System is a field instrument that uses ground-penetrating radar (GPR) technology in a new and novel way to non-invasively determine both the internal structure of a tree and its structural root mass. These are two separate measurements of the health and structural integrity of a tree. The advanced-technology and patented TRU system consists of a portable, battery-powered data acquisition unit and an off-line data analysis software module.

Data Acquisition Computer

  • Digitizes and stores the radar waveforms in ruggedized pen-tablet style of computer that controls the radar antenna
  • Presents a real-time graphical representation on a display capable being viewed in bright sunlight
  • Radar electronics are housed in five pound (1.8 kg), hand-held rectangular box
  • Antenna is held and moved along the bark and automatically generates a pulse for every 0.2 inch (5 mm) of movement around the tree`s periphery
  • Data acquisition computer and antenna can be mounted on customized deployment cart to easily conduct root surveys (below)
  • Set up requires 5 minutes and a complete 360-degree peripheral scan around the trunk (at a given elevation) can be done in 1 minute.
  • The rechargeable batteries provide at least six hours of continuous use.
  • No trunk preparation is required. The trunk is typically scanned at multiple elevations to accurately map a decay column`s advance along the trunk.
  • Subsurface root scans can be done in 30 to 60 minutes to map the structural root density, location and depth.
  • The entire TRU system can be transported in either two carrying cases or in a back pack and small carrying case.
