摘要
为了解决基于Surfer软件自带数字化功能生成的瞬变电磁法扇形超前探测白化文件的弊端,提出了一种精确快速生成Surfer白化文件的新方法,并分析了Surfer白化文件数据结构,定义了标准白化文件概念,研究了精确快速生成Surfer白化文件的数学原理及算法,编写了相应的Matlab程序。通过与基于Surfer软件自带数字化功能生成白化文件方法对比实验表明:当白化处理1个扇形剖面时,该方法生成白化文件用时是传统方法的1/247且白化采样点定位高度精确,而传统方法白化采样点定位偏差极大;当有多个扇形超前探测剖面需要白化处理时,更能体现提出的Surfer白化文件精确快速生成方法的优越性、高效性。
This paper presented an accurate and rapid new method of producing surfer blanking file in order to solve the malpractices of production blanking file of TEM sector advance detection about self-contained digital function of the surfer software, and analyzed the data structure of surfer blanking file, and defined the concept of standard blanking file, and studied the mathematical principle and algorithm of the accurate and rapid production of surfer blanking file. Additionally, a corresponding Matlab program is written in this paper. Compared with the traditional method of producing blanking file about the digital function of the surfer software, the comparison experiment shows that: when blanking processes one sector-shaped section, the time of producing blanking file is 1/247 of the traditional method, and its position of blanking sampling point is highly accurate, but positioning error of blanking sampling point of the traditional method is large;when blanking processes multiple sector-shaped sections, it can also reflect the advantages and efficiency of the accurate and fast generation method of surfer blanking file.
