Pipe wall thinning was evaluated quantitatively by using time domain measurement of Position of pipe wall thinning was evaluated quantitatively by using time domain measurement of microwaves, and the influence of the measurement sensitivity due to the frequency band of microwaves was investigated. Microwave signals having different frequency bands of 10MHz to 40GHz and 10MHz to 67GHz were transmitted from the terminal o f a straight line copper pipe, and the change in the response of the reflected signals ...
