| 摘 要： | 针对钴结壳具体赋存环境和开采技术要求,作者提出了利用Morlet小波信号包络和高斯函数曲线及能量相关性算法对拟设计的微地形探测方法接收到的超声回波信号进行分析与计算。由实验初步验证,利用该算法计算出来的被测对象位置精度及误差稳定性均高于传统的超声波单波束多探头探测方法。

| Abstract: | Aiming at cobalt crusts'existing circumstances and mine-technology requirement,the authors put forward a method to analyze and calculate received ultrasonic echo signal based on the Morlet wavelet signal envelope and Gauss function curve as well as energy relativity methods.Primary experiment shows that the precision and error reliability of measured object based on this algorithm are higher than traditional ultrasonic single beam and multi transducer method. |
