Many proven methods, like radar, electric resistance and magnetism, have been widely used to detect underground buried objects, as proven detection devices.
An infrared radiometer (IR) has been widely used to detect an internal flaw of industrial structural components, as a remote sensing nondestructive method. And the method was remarkedly developed with aid of the thermal image method (TIM).
Injecting the solar and artifical combustion radiation energy on a ground surface, the near-underground buried objects was detected by observing nonuniform and discontinuous distribution of the radiation temperature above the object by means of the IR.
The IR method was used to examined experimentally to detected the buried tomb in Komochi village, Gunma prefecture, as an application study. We could observed the non-uniform distribution of the radiation temperature above the tomb, as in case of test results by the radar and electric tests.
