研究了在横、纵向同时求模糊关系的高层次模糊模式识别方法，并且把这一方法应用于EH－4电磁测探资料的解释。对于大地电磁测深方法，干扰比地震或其它可控源电磁法要强，利用单一参数解释就会不够准确。EH－4大地电磁测深仪，在记录电磁场的5个分量后，可以现场处理出14个反映地电参数的信息。利用我们研制的模糊模式识别方法，对这14个信息因子进行地电参数的解释，收到了较好的效果。
The high-level fuzzy pattern recognition method is studied in the aspect of horizontal and vertical fuzzy relations at the same time, and this method is applied to the interpretation of EH-4 electromagnetic survey data. For MTD methods, the interference is stronger than earthquakes or other controllable source electromagnetic methods, interpretation using a single parameter may not be accurate enough. EH-4 terrestrial electromagnetic sounder, after recording the five components of the electromagnetic field, can process 14 pieces of information reflecting the geoelectric parameters on the spot. Using our fuzzy pattern recognition method, we interpret the geoelectric parameters of these 14 information factors and receive good results.
