通过地表高程信息计算最佳采集深度是解决钴结壳开采贫化问题的关键技术之一。根据钴结壳的赋存环境和开采方法，提出了一种摆动式超声单波束微地形探测方法。为了检验该方法的可行性，成功搭建了实验台，并验证了该实验台的垂直探测精度可达到厘米级；提出了一种改进型数据加窗算法，进一步提高了高程异常值被剔除的准确性；提出了采用线性相关系数法解决支持向量线性与非线性回归的选择问题；提出并证明了高斯径向基参数σ可根据测线上的坡度、坡长信息来确定。

One of the key technologies to solve the dilution problem of cobalt crust is to calculate the best exploitation depth by surface elevation information. A single-beam swing ultrasonic micro-terrain detection method was proposed based on occurrence of cobalt crust and mining method. To test the feasibility of the method a laboratory bench has been successfully built, and the fact that the detection accuracy of vertical bench can achieve centimeter level has been verified. Subsequently. an improved data windowing algorithm to further improve the accuracy of removing exceptional elevation value was submitted; linear correlation coefficient method was adopted to choose linear and nonlinear regression support vector.It is proposed and proved that Gaussian radial basis function parameter σ can be determined according to the slope, slope length information on measuring line.
