altitude datum การใช้

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
The authors use a ultrasonic transducer emit ultrasonic to simulated seabed tiny terrain , then analyze and calculate the relativity of amplitude according to the time , phase and amplitude etc included in echo signal and making using of the relativity of amplitude characteristics , at last gain the real - time altitude data of tiny terrain for deep - sea cobalt crusts mining in order to provide the parameter of best cutting depth for the intellectualized mining of excavating head
