Outline of Final Research Achievements

A nondestructive and small FMCW radar apparatus for scanning of the wooden wall to evaluate inner structure and bio-degradation progressed in the wall was developed. The parts in the wall such as wooden posts and beams, metal plate connectors were recognized as 2D and 3D images. The moist area was also recognized, and this suggests that the area of potentiality of bio-degradation can be detected by this apparatus.
