Frequency Domain Reflectometry (FDR)

Frequency Domain Reflectometry (FDR) is a technique used to analyze the properties of materials and detect defects in cables or structures. It sends a range of radio frequency signals down a line or through a material and measures how these signals reflect back. By analyzing the variations in the reflected signals, FDR can determine the location and nature of faults, moisture presence, or material changes. This method is valuable in industries like telecommunications, construction, and environmental monitoring, enabling quick and precise assessments without needing direct access to the entire length of the material being tested.
