Exploration Method for Tiny Terrain of Seabed Cobalt Crust Based on Energy Relativity Search

On the premise that the basal transducer layout was designed according to the requirements of deep-sea exploring surroundings and technology on the basis of the hardware structure and data collecting ways of interferometric sonar, the echo signal by energy relativity search is analyzed and calculated, altitude data of the tiny terrain on the seabed under real-time irradiation of ultrasonic is gained as to provide parameters of best cutting depth for intellectualization of the seabed mining vehicle timely and promptly. Theoretical analyses and lab experiments have proved that this method is feasible.
