摘　　要：通过超声波换能器向模拟海底微地形发射超声波,根据回波信号包含的时间、相位和幅度等信息,利用幅度特征相关性进行分析和计算,得出深海钴结壳开采所需要的实时微地形高程数据,为采掘头智能化开采提供最佳切削深度参数。经过理论分析与实验室初步验证,结果表明该方法切实可行。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 ete 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. The results of theoretic analysis and indoor primary proving test indicate that this method is practical and feasible.
