(1)TDR (Time Domain Reflectometry)
TDR technology was used to detect the cable faults in CATV industry, and it was firstly applied with geomaterials in the 1970s. This technology is employed in geotechnical engineering and environmental engineering recent decade.
You may take 1D radar as a early form of TDR, and you can read reference listed below or read "Introduction to TDR" if you want to know furthermore.
