The signal detection unit 10 detects, as a signal, an acoustic echo derived from an explosion sound emitted from a sounding bullet thrown down to the sea floor as it is echoed by a protrusion on the sea floor. Meanwhile, the signal discrimination unit 20 determines, from the result of frequency analysis of the detected signal, whether a resonance sound caused to occur by a space filled with gases is included in the acoustic echo, and thereby discriminates whether or not the protrusion on the sea floor is an underwater sailing object. At this time, it is determined that the resonance sound is included when, with regard to the material of an airtight chamber of the assumed underwater sailing object, the signal strength of a frequency band equivalent to a wavelength that is twice the estimated length of the airtight chamber is larger than other frequency strength.SELECTED DRAWING: Figure 1
