  • Submarine resource exploration system, transmission device, reception device, signal processing device, signal processing method, electrical exploration method, electromagnetic exploration method, and program
    Patent number: 11099291
    Abstract: A transmission device of a submarine resource exploration system includes a transmission unit which transmits a predetermined transmission artificial signal transmitted in order to perform exploration of submarine resources in water using water as a medium. A reception device includes a reception unit which receives a composite signal of a received artificial signal representing a signal propagated to the reception device using water as a medium in the transmission artificial signal, and a self-potential propagated to the reception device using water as a medium due to a potential anomaly generated due to submarine resources. A signal processing device includes a signal processing unit which separates the composite signal into the received artificial signal and the self-potential.
