PROBLEM TO BE SOLVED: To provide a non-destructive measuring system for measuring easily a diameter of an irregular-shaped reinforcement in a reinforced concrete structure.;SOLUTION: The non-destructive measuring system is provided with a step for scanning a surface of the reinforced concrete structure along the irregular-shaped reinforcement by an electromagnetic wave radar provided with a transmission antenna and a reception antenna, and for repeating transmission and reception of an electromagnetic wave in every prescribed pitch, a step for storing time-serially propagation times of the electromagnetic wave reflected from the irregular-shaped reinforcement, a step for frequency-analyzing a time-serial data of the stored propagation times, a step for finding an average interval of nodes in the irregular-shaped reinforcement, based on the maximum peak position by the frequency-analysis, and a step for determining the reinforcement diameter, based on a prescribed correspondence table, according to the average interval.;COPYRIGHT: (C)2009,JPO&INPIT
