| 摘 要： | 在分析探讨影响航空电磁测量数据质量主要因素的基础上,提出了场值标定,相位校验改正等零水平漂移改正方法,研究开发了一套适合航空电磁法数据处理与图示的方法技术。通过对3万多测线公里航空电磁资料的处理与图示,证明了方法的有效性,取得的视电阻率图像反映了各测区浅层电性分布特征,为地质填图提供了新的资料。

| Abstract: | Based on an analysis of the major factors affecting the quality of data obtained in aeroelectromagneticsurvey, this paper has put forward zero horizontal drift correction methods such as field value standardization andphase check and correction, studied and developed a suite of techniques suited to data - processing and graphical representation for aeroelectromagnetic method. The processing and graphical representation of aeroelectromagnetic dataof over 30 000 traverse kilometers demonstrate the effectiveness of the techniques, and the apparent resistivity images obtained reflect characteristics of shallow electric distrbution, thus providing new data for geological mapping. |

| Keywords: | aeroelectromagnetic method zero horizontal drift data-processing apparent resistivity map |
