  • Publication number: 20240142610
    Abstract: An exploration method according to the present disclosure includes: a step (S11) of disposing, in a pipeline (PL) that allows a plurality of manholes (MH) to be interconnected, an electromagnetic wave receiving/transmitting device (1) that transmits an electromagnetic wave and receives a reflected electromagnetic wave that is a reflected wave of the electromagnetic wave; a step (S13) of transmitting the electromagnetic wave; a step (S14) of receiving the reflected electromagnetic wave that is the reflected wave of the electromagnetic wave; and a step (S18) of calculating an intensity distribution of the reflected electromagnetic wave on the basis of an intensity of the reflected electromagnetic wave and a round-trip propagation time from when the electromagnetic wave is transmitted to when the reflected electromagnetic wave is received.
