UNDERWATER RESOURCES EXPLORING METHOD AND SYSTEM THEREOF

摘要

PPROBLEM TO BE SOLVED: To provide an underwater resources exploring method and its system which can discover underwater resources of desired form, irrespective of the attitude or the buried circumstances of resources. PSOLUTION: Sonic wave 4 is irradiated toward exploration direction in underwater W. Scattered wave 5, from unknown underwater resources 3, is received in a plurality of places surrounding the exploration direction. On the basis of the incoming period of the scattered wave 5 received by multi-static measurement at the plurality of places, the scattered wave received level and scattered pattern, the location of the unknown underwater resources 3 as the cause of scattering and the form and the attitude of the resources 3 are presumed.
