<p>PROBLEM TO BE SOLVED: To provide a detecting apparatus, for an underground object, in which a plurality of radio waves at different frequencies are radiated by an antenna part formed by integrating antennas used to radiate radio waves at a plurality of different frequencies and which can receive a reflected signal from the surface of the ground or from a buried object as different from a detecting apparatus in which radio waves are radiated by using a plurality of antennas separated and arranged independently and in which a reflected signal from an object buried near the surfaced of the ground is received so as to detect the buried object. SOLUTION: An antenna part 3 is installed in such a way that a plurality of antennas which are composed of a conductor having a slit and a plurality of dielectrics are overlapped with each other so as to be integrated and that a plurality of radio waves are radiated from the antenna part 3 toward a buried object from the same place and in the same pattern so as to be received. The amplitude and the phase of a reflected signal received by the antenna part 3 are detected. On the basis of their detected electric signals, a signal processing operation 5 in which different frequencies are correlation-processed is performed. Thereby, the detecting accuracy of the buried object is enhanced.</p> |
