PROBLEM TO BE SOLVED: To remove the effect by a reflected wave or reflected wave sequence present in the same time band by calculating the difference between each determined data value sequence and the average value of each data value sequence. SOLUTION: An electromagnetic wave is transmitted and received through a transmitting antenna 15 and a receiving antenna 17, and a hyperbolic received wave sequence from a buried matter T formed by the emitting and receiving angles of the electromagnetic wave is extracted by removing a repeated horizontal reflected wave sequence which is a transient response of ground surface reflected wave. For this, paying attention to the data value sequence in the receiving point, the most effective horizontal range for calculating the average value of data value sequences is determined, and the calculation of subtracting the average value sequence in the effective range around the receiving point from the data value sequence in the receiving point while keeping the continuity of the data value sequence in the receiving point every sequence is performed.
